Question

A hydraulic jack has an input piston of area 0.0520 m² and an output piston of area 0.740 m². How much force (in N) on the input piston is required to lift a car weighing 1.70 ✕ 10⁴ N?

? = N

Answer 1

Given:

Input piston area,

Output piston area,

Weight of the car,

------------

A hydraulic jack works according to the Pascal's law.

Pascal's Law states that the pressure change in a confined incompressible fluid is transmitted equally throughout the fluid.

So pressure at input piston is equal to pressure at output piston

Pressure = Force/Area

Force at output piston is the weight of the car
