Formula based on Pascal’s law

Pressure on the small piston = Pressure on big piston
i.e. P1 = P2

F1 = F2 = F3 =F4

A1 A2 A3 A4

Q. Why is hydraulic press is called a force multiplier?
Ans: Hydraulic press is constructed on the basis of Pascal’s Law.

So, according to Pascal’s law,
Pressure on the small piston = Pressure on big piston

i.e. P1 = P2
or, F1 = F2

A1 A2
or, F1 x A2 = F2 x A1

Since, A2 > A1
Thus, F2 > F1

Hence, a hydraulic press is a force multiplier.
