What is a hydraulic press? Definition. A
0:03
hydraulic press is a machine that uses
0:05
liquid pressure to multiply force,
0:07
allowing a small applied force to
0:09
produce a much larger output force.
0:12
Explanation: A hydraulic press works
0:14
based on Pascal's principle, which
0:17
states that pressure applied to a
0:19
confined liquid is transmitted equally
0:21
in all directions. The press consists of
0:25
two cylinders filled with liquid and
0:27
connected together each having a piston
0:29
of different area. When a small force is
0:32
applied to the smaller piston, it
0:35
creates pressure in the liquid. This
0:37
pressure is transmitted to the larger
0:39
piston producing a much greater force.
0:43
This is why hydraulic presses are used
0:45
to lift heavy loads or compress
0:47
materials with ease. Imagine. Imagine
0:50
pressing a small syringe connected to a
0:53
much larger syringe filled with liquid.
0:56
When you push the small syringe, the
0:58
larger one moves with a stronger force.
1:01
That is how a hydraulic press works. In
1:03
simple terms, a hydraulic press makes a
1:06
small force powerful enough to lift or
1:08
press very heavy objects. Formula or
1:11
concept. A hydraulic press operates on
1:14
equal pressure transmission in a liquid.
1:17
Pressure equals force/ area. For a
1:20
hydraulic press, forces area equals
1:23
forces area. Where forces equals force
1:27
applied on the small piston. Area equals
1:30
area of the small piston. Forces equals
1:33
force produced on the large piston. Area
1:36
equals area of the large piston. Key
1:39
points. Works on Pascal's principle.
1:42
Uses incompressible liquids. Multiplies
1:44
force. has to pistons of different
1:47
areas. Widely used in industry.

education. Question: Why does a
2:08
hydraulic press produce a larger force
2:10
at the bigger piston? Answer. It
2:13
produces a larger force because the same
2:15
pressure acts on a larger area resulting
2:18
in a greater force. Solved problem
2:21
question and answer. Question. A force
2:24
of 50 un is applied to a small piston of
2:27
area 0.01 square m. What force is
2:31
produced on a large piston of area 0.5
2:35
m? Answer forces equals 50. Area equals
2:40
0.01 01 m. Area equ= 0.5
2:45
m. Forces equals forces time area. Area
2:49
forces equals 50 * 0.5
2:53
0.01.
2:54
forces equals 2500N.
