What is a Lever Balance in Physics?

1. What is a Lever Balance?

Lever balance in physics is a device where the forces acting on the lever are in equilibrium or balance. Therefore, lever balance obeys the principle of Equilibrium of forces. Thus, it means that the sum of the clockwise moments is equal to the sum of the anticlockwise moments around the fulcrum. In other words, the lever is stable and does not rotate in any direction. To achieve lever balance, we must carefully control the force, distance, and direction of the applied forces.

Lever balance in physics
Lever balance in physics

2. Explanation

A lever balance in physics is a simple device that consists of a rigid bar which rotates around a fixed point called the fulcrum. The lever can amplify or reduce the applied force, change the direction of the force, or convert the force into motion.

The principle of lever balance is based on the idea that the force and the distance from the fulcrum are inversely proportional. This device amplifies the principle of equilibrium of forces. Therefore, this means that the longer the distance from the fulcrum, the less force we need to balance the lever, and vice versa.

Lever balance is an essential concept in physics and engineering that plays a crucial role in designing and operating a wide range of systems and devices. Whether you are building a simple machine or designing a complex mechanism, understanding the principles of lever balance is critical to ensuring optimal performance and safety. In this article, we will explore the fundamental concepts of lever balance, the different types of levers, and their applications in various fields.

3. The Three Types of Levers

There are three types of levers based on the relative positions of the fulcrum, the effort force, and the load. These are:

a. First-Class Levers

In first-class levers, the fulcrum is located between the effort force and the load. Examples of first-class levers include scissors, pliers, and seesaws. First-class levers can amplify or reduce the applied force, change the direction of the force, or balance the lever.

b. Second-Class Levers

In second-class levers, the load is located between the fulcrum and the effort force. Examples of second-class levers include wheelbarrows, bottle openers, and nutcrackers. Second-class levers can amplify the applied force and generate a large output force with a small input force.

c. Third-Class Levers

In third-class levers, the effort force is located between the fulcrum and the load. Examples of third-class levers include fishing rods, tweezers, and shovels. Third-class levers can increase the distance or speed of the applied force but require a larger input force.

4. Principles of Lever Balance

To achieve lever balance, we must consider the following principles:

The Principle of Moments

The principle of moments states that the sum of the clockwise moments around the fulcrum is equal to the sum of the anticlockwise moments. Therefore, the forces and distances must balance to for us to achieve equilibrium.

Center of Mass

The center of mass is the point where the mass of the object is evenly distributed. In this case, we need to align the center of mass of the lever and the load with the fulcrum.

Torque

Torque is the rotational force generated by the lever. We can calculate it by multiplying the force applied by the distance from the fulcrum. The direction of the torque depends on the direction of the force and the position of the fulcrum.

5. Applications of Lever Balance

Lever balance has many applications in various fields, including:

a. Simple Machines

Simple machines, such as levers, pulleys, and inclined planes, use lever balance to amplify or reduce the applied force. These machines are used in everyday life, such as in door handles, bottle openers, and scissors.

b. Engineering and Design

Lever balance is essential in engineering and design, where levers are used to operate heavy machinery, such as cranes, forklifts, and excavators. Engineers also use levers to design mechanisms that can convert linear motion into rotational motion, such as in engines and turbines.

c. Human Anatomy and Physiology

The human body also uses levers to generate and control movement. The bones, muscles, and joints in the body act as levers that allow us to perform various movements, such as walking, running, and jumping.

6. Advantages and Limitations of Levers

The advantages of levers include their ability to amplify or reduce the applied force, change the direction of the force, or convert the force into motion. Levers are also simple and easy to use, and they require minimal maintenance.

However, levers also have limitations, such as their inability to generate force without an input force. They are also limited by the strength and rigidity of the materials used to construct them.

7. Lever Balance in Action

To see lever balance in action, let’s consider the example of a seesaw. In a seesaw, two people sit at opposite ends of a long plank, which acts as the lever. The fulcrum is located at the center of the plank. When one person pushes down on their end, the other end rises, and the seesaw tilts. The seesaw reaches a state of equilibrium when the forces and distances are balanced, and both ends are at the same height.

What is Beam Balance Used For

What is a beam balance?

A beam balance is a weighing instrument used to determine the weight of an object by balancing it against a known weight. It consists of a horizontal beam that is supported by a fulcrum, with two pans suspended from each end. Hence, the object to be weighed is placed on one pan, while calibrated weights are placed on the other until the beam is balanced.

What is Beam Balance Used For

A brief history of beam balances

We can trace the earliest form of beam balances to ancient Egypt and Rome. In that period, they were used for commercial and trade purposes. Additionally, there was a continuous improvement of the design up until the 18th century when John Mitchell invented the lever balance, which was more precise and reliable than its predecessors. Since then, beam balances have been widely used in scientific research, manufacturing, and other fields that require accurate measurements.

How does a beam balance work?

A beam balance works on the principle of equal lever arms. When we place an object on one pan. The weight of that object will exert a downward force. Hence, this downward force is transmitted through the beam to the fulcrum. On the other hand, we will continue to adjust the calibrated weights on the other pan. We will not stop until we balance the it perfectly. At this point, the weight of the object is equal to the sum of the calibrated weights.

Types of beam balances

There are several types of beam balances, including:

Lever balance

The lever balance is the most common type of beam balance. It consists of a lever with arms of unequal length, with the shorter arm supporting the weighing pan and the longer arm supporting calibrated weights. Thus, the lever is balanced by moving the weights until the pan is level.

Roberval balance

The Roberval balance uses two equal-length arms and two parallel weighing pans. Therefore, we place the load we intend to measure on one pan. Subsequently, we can place the calibrated weights on the other. Thus, we will get the result of the balance by adjusting the weights until the pans are level.

Borda-Carnot balance

The Borda-Carnot balance uses a vertical beam and two equal-length arms. The arms support two weighing pans. Therefore, we can achieve the balance by continues adjusting of the calibrated weights until the pans are level.

Parts of a beam balance

A beam balance consists of several parts, including:

Beam

The beam is a horizontal bar. There is a fulcrum that supports it.

Pan

The pan is the platform where we place the object to we intend weigh.

Knife edge

The knife edge is the point where the beam pivots on the fulcrum

Pointer

When you look closely, you will see the attachment between the pointer and the beam. Thus, the pointer indicates the position of the beam relative to a reference point.

Fulcrum

The fulcrum is the pivot point that supports the beam.

How to use a beam balance

Using a beam balance is a simple process. Follow these steps:

Gold Leaf Electroscope: How It Works and Its Applications

What is Gold Leaf Electroscope?

The Gold Leaf Electroscope is a simple but powerful tool used for detecting the presence and magnitude of electric charges. It was invented by British physicist Abraham Bennet in the 18th century and has been used by scientists and engineers ever since. Additionally, the device consists of a glass jar with a metal rod in the center, attached to two thin strips of gold leaf.

GOLD-LEAF ELECTROSCOPE

When a charged object is brought near the metal rod, the gold leaves move apart due to the repulsion of like charges. In this article, we will explore the Gold Leaf Electroscope in detail, including its components, working principle, and applications in various fields.

Components

The Gold Leaf Electroscope consists of the following components:

  1. Glass jar. This serves as the container for the electroscope and provides insulation for the components.
  2. Metal rod. The metal rod, usually made of brass or aluminum, connects the gold leaves through a thin wire and serves as the central component of the electroscope.
  3. Gold leaves. Thin strips of gold, usually 3-4 cm long, attach to the metal rod and are very thin and lightweight, making them sensitive to the slightest charge.

How does Gold Leaf Electroscope Work?

A Gold Leaf Electroscope is a simple device used to detect and measure electric charges. It consists of a metal rod with two thin gold leaves attached at the bottom. Here is how it works:

  1. Charging: When an object with an electric charge, such as a negatively charged rod, is brought close to the metal rod of the electroscope, it induces an opposite charge in the leaves due to the principles of electrostatic induction. The negative charge from the rod pushes electrons away in the leaves, leaving them with a positive charge.
  2. Repulsion: Like charges repel each other, so when the leaves become positively charged, they try to move away from each other.
  3. Separation: The repulsion between the leaves causes them to spread apart, creating an angle between them. The greater the charge on the metal rod, the more the leaves separate.
  4. Measuring charge: By observing the angle of separation, you can estimate the amount of charge on the object that initially influenced the electroscope. The larger the angle, the higher the charge.
  5. Grounding: To discharge the electroscope and bring the leaves back together, you can touch the metal rod with your hand. This process allows any excess charge to flow into or out of the Earth, balancing the electroscope’s charge.

Working Principle of the Gold Leaf Electroscope

This device works on the principle of electrostatic repulsion. Bringing a charged object near the metal rod repels the electrons in the metal rod by the like charge on the object. This will cause them to move to the ends of the gold leaves. Subsequently, this creates a repulsive force between the like charges on the gold leaves. It will now cause them to move apart. Therefore, you can estimate the amount of charge on the object by the amount of separation between the gold leaves.

The Gold Leaf Electroscope works based on the principles of electrostatics. It uses the repulsion between like charges to detect the presence and measure the magnitude of electric charges in objects. When charged, the leaves move apart, and by observing this separation, you can assess the charge’s strength. Touching the rod with your hand can reset the electroscope for further use.

Applications

The Gold Leaf Electroscope has many applications in various fields. Some of the most common applications are:

  1. Physics. Physicists use it to detect the presence and magnitude of electric charges, as well as to measure the potential difference between two points.
  2. Chemistry. Chemists use it to detect the presence of ions and other charged particles in their experiments.
  3. Electrical engineering. Electrical engineers also use it to test the performance of electronic components and circuits.
  4. Medical research. Medical researchers use it to detect the presence of charged particles in biological samples..

Summary

The Gold Leaf Electroscope is a simple but powerful tool used for detecting the presence and magnitude of electric charges. Its sensitivity and versatility have made it an essential tool in various fields, including physics, chemistry, electrical engineering, and medical research. Therefore, by understanding the components and it’s working principles, scientists and engineers can continue to use this valuable tool to advance their research and experiments.

Frequently Asked Questions (FAQs)

Can we use the Gold Leaf Electroscope to detect both positive and negative charges?
Yes, it can detect both positive and negative charges.

What is the sensitivity of the Gold Leaf Electroscope?
It is very sensitive and can detect charges as small as a few micro coulombs.

How can we charge the Gold Leaf Electroscope?
We can charge it by bringing a charged object near the metal rod. We can also connect the metal rod to a high-voltage source.

How to Use a Micrometer Screw Gauge: A Guide for Beginners

What is Micrometer Screw Gauge?

Micrometer screw gauges, also known as micrometers, are precision measuring instruments used in many industries, including engineering, manufacturing, and science. We commonly use these tools to measure the thickness or diameter of small objects with high accuracy. If you’re new to using micrometer screw gauges, you may find it intimidating at first. However, with a little bit of guidance, you’ll be able to master this tool in no time. In this article, we will provide you with a comprehensive guide on how to use a micrometer screw gauge.

How to Use a Micrometer Screw Gauge
How to Use a Micrometer Screw Gauge

We use micrometer screw gauges to measure the thickness or diameter of small objects with high accuracy. They consist of a frame, anvil, spindle, sleeve, thimble, ratchet stop, and locking clamp. Additionally, micrometers can measure in both metric and imperial units and are available in different types, such as outside micrometers, inside micrometers, and depth micrometers. We apply them in various industries, including engineering, manufacturing, and science.

Types of Micrometer Screw Gauges

1. Outside Micrometers

Outside micrometers is for measuring the outer diameter of objects, such as wires, tubes, and shafts. They also consist of a U-shaped frame, an anvil, and a spindle. Furthermore, the anvil is stationary, while the spindle moves towards it to make contact with the object we are measuring. Finally, we can then read the measurement from the sleeve and thimble scales.

2. Inside Micrometers

The use of inside micrometers is to measure the inner diameter of objects, such as pipes and holes. They consist of a T-shaped frame, an anvil, and a spindle. Moreover, the anvil is adjustable and moves towards the spindle to make contact with the object we want to measure. As soon as it makes contact, we can then read our measurement from the scales on the sleeve and thimble.

3. Depth Micrometers

We also use depth micrometers to measure the depth of objects, such as holes and slots. They consist of a base, a rod, and a measuring head. The measuring head contains a spindle and an anvil, which can be adjusted to reach the bottom of the hole or slot. We can now take our measurements.

Parts of a Micrometer Screw Gauge

To understand how to use a micrometer screw gauge, it’s important to know the different parts of the tool and their functions.

1. Frame

The frame is the main body of the micrometer and provides support for the other parts. It consists of two arms connected by a bridge.

2. Anvil

The anvil is the stationary part of the micrometer that the object being measured rests against.

3. Spindle

The spindle is the moving part of the micrometer that makes contact with the object we are measuring. It is attached to the thimble.

4. Sleeve

The sleeve is the stationary outer part of the micrometer that contains the sleeve scale.

5. Thimble

The thimble is the rotating inner part of the micrometer that contains the thimble scale.

6. Ratchet Stop

The ratchet stop is a small lever that prevents the over-tightening of the micrometer and ensures consistent measurement pressure.

8. Locking Clamp

The locking clamp is used to lock the micrometer in place once the measurement has been taken.

How to Read a Micrometer Screw Gauge

To read a micrometer screw gauge, you need to use both the sleeve and thimble scales.

Using the Sleeve Scale

The sleeve scale is the stationary outer part of the micrometer that contains markings in millimeters or inches. The sleeve scale is divided into 10 or 20 equal parts, each representing a specific measurement unit.

Using the Thimble Scale

The thimble scale is the rotating inner part of the micrometer that contains markings in millimeters or inches. The thimble scale is divided into 25 or 50 equal parts, each representing a fraction of a measurement unit.

Adding the Reading

To get an accurate measurement, you need to add the readings from the sleeve and thimble scales. The sleeve scale reading is obtained from the first line that coincides with the thimble scale. The thimble scale reading is obtained from the line that coincides with the axial line of the sleeve.

How to Measure with a Micrometer Screw Gauge

To measure with a micrometer screw gauge, you need to follow these steps:

Preparing the Micrometer

Ensure that the micrometer is clean and calibrated before use. Use the locking clamp to hold the spindle and anvil together.

How to Read a Vernier Caliper

Introduction

Calipers are instruments we use to measure the length of a metal object. We apply vernier calipers in conditions where the meter rule may not give us a precise measurement of those objects. In the past, calipers were also used to measure direction. In this article, you will learn the best method on how to read a vernier caliper correctly. However, before we delve into explaining vernier calipers, we need to first understand what are calipers.

The history of calipers is a very long one because scientists have shown traces of evidence as early as 202 BC to 220 AD in China. Additionally, the Chinese have used calipers to measure objects and for every caliper they produce, they make sure that the manufacturing date of that caliper is engraved on it.

We have two types of calipers

  1. Engineer’s calipers
  2. Vernier caliper

Engineer’s calipers: This type of caliper is of two types, we have External and Internal calipers. The external calipers are created with two jaws like that of a crab, it is meant to hook the external length (diameter) of an object in form of a circle like the diameter of a wood.

The internal caliper measures the exact opposite of the external calipers. The hooks of internal calipers are projected outward. Also, Internal calipers can be used to measure the diameter of a pipe from the inside by clipping the two jaws of the caliper from the inside of the pipe.

After measuring the diameter of the object, you tighten the knot of the two jaws on the caliper to make sure that your measurement does not change.

A meter rule is then used to confirm the reading of the length of the caliper.

What is Vernier Caliper

A vernier caliper is an instrument that helps users to find the exact measurement 0f an object. The history of the application of the vernier caliper began in 1631 by a French mathematician called Pierre Vernier (1584 – 1638). Vernier calliper can give a more accurate measurement than meter rule.

we can measure the internal and external radius or diameter of an hollow material like pipe and can. We can use vernier caliper to record internal or external diameter of an object.

Diagram of Vernier Caliper

Here is a diagram and picture of vernier caliper

Parts of Vernier Caliper

Here are parts of the vernier caliper you need to know:

  • What is the Vernier Scale of a vernier caliper:

     As seen on the diagram above, the vernier scale is a scale with fewer calibrations on the instrument. The body where the vernier scale appears is shorter and on top of the longest calibrations. The body of the vernier scale has two jaws and it slides over the main calibrations. Vernier scale measures the fraction of the smallest division on the main scale. The two jaws of the vernier scale are from the right-hand side

  • What is the Main Scale of a vernier caliper: 

    The main scale is the main body of the vernier caliper. The body of the vernier scale is resting on the calibrations of the main scale. The calibrations on the main scale are longer. You slide the body of a vernier scale over that of the main scale to adjust the jaws to the size of the material you want to measure. The two jaws of the main scale are from the left-hand side.

  • Locking Nut of a Vernier caliper:

     After adjusting the jaws of the vernier scale and main scale, you tighten the locking nut to avoid recording wrong measurements.

  • Jaws a Vernier caliper:

     There are 4 jaws on the vernier caliper. The two jaws from the right are for the main scale, while the two jaws from the left are for the main scale. You are to push the rotor (on the vernier scale) forward or backward to clip the jaws of the vernier caliper with the object you are measuring. We also have the upper and lower jaw of the vernier caliper. The upper jaw is for measuring the internal diameter of a cylindrical object while the lower jaw is for measuring the external diameter of an object (like a ball).

What is the Vernier Caliper Least Count Formula

To find the vernier caliper least count formula. we apply the formula below:

Least Count, X = Smallest reading on the main scale (Y) / Number of divisions on the vernier scale (Z)

X = Y / Z

and if Y = 1 millimeter

Z = 10 divisions

we now have

X = Y / Z = 1 mm / 10 = 0.1 mm or 0.01 cm

Therefore the least count formula of a vernier caliper is 0.1 mm or 0.1cm

Explanation: We need to understand that the vernier caliper consists of ten (10) divisions, and has a length of 0.09cm or 0.9mm.  To get the fractions of the smallest unit on the main scale, we divide the smallest reading on the main scale (Y) by the number of divisions on the vernier scale (Z)

Vernier Caliper Reading

how to read a vernier caliper

physicscalculations.com

Here is the simplest method of understanding vernier scale reading:

Part 1

  1. Unscrew the lock nut on the vernier caliper
  2. Adjust the jaws of the vernier caliper to check for zero error. Connect the zero mark on the vernier scale graduation with the zero mark on the main scale. If the zeros on both scales do not meet, you need to take note of the zero error. If they both coincide, you don’t have any problem.
  3.  Now, attach the object to the right jaw (note: the external jaw is for reading the internal diameter like a cylinder, while the external jaw is for reading the external diameter like a ball).
  4. Tighten the lock nut
  5. And look into the open window of the vernier scale, will notice a few calibrations of the main scale.
  6. Remember that we have 10 divisions on the vernier scale (0.09 mm) and they start from zero.
  7. Before the zero mark on the vernier scale, look for the last calibration on the main scale within the window (a number on the main scale that came before the zero mark on the vernier scale).

Part 2

  1. Record that number on the main scale as 5.0 cm
  2. Now, look for the mark on the vernier scale that connects with the mark on the main scale
  3. Start counting the marks on the vernier scale until you reach the mark where both the vernier and main scale coincide (0.06 cm)
  4.  Finally, you add the readings of the main scale and that of the vernier scale together = 2.0 cm + 0.03 cm
  5. Our vernier caliper reading is now 2.03 cm or 20.3 mm
  6. Vernier calipers have a reading accuracy of 0.01 cm or 0.1mm

Applications of Vernier Caliper

  1. We use vernier calipers in laboratories(during research) in the area of expansivity and to also understand the diameter of cylindrical objects
  2. This instrument is also very important in the medical field. It helps to measure the precise length of a medical instrument before it is deployed to the hospitals.
  3. We apply Vernier caliper in industries to get an exact dimension of instruments like pipe and other materials.
  4. Vernier caliper is very important in car industries to measure the dimension of wheels and other important equipment
  5. We also apply vernier caliper in our schools (for the purpose of learning)
