Question

A hydraulic lift is made by sealing an ideal fluid inside a container with an input piston of cross- sectional area 0.004 m2, and an output piston of cross-sectional area 2 m2. The pistons can slide up or down without friction while keeping the fluid sealed inside. What is the maximum weight that can be lifted when a force of 50 N is applied to the input piston?

Answer 1

2500N

Step-by-step explanation:

Like the law of conservation of energy( analogous to it ), Input pressure and output pressure will be equal, pressure is defined as force per unit area. here in this scenario

input pressure is equal to output pressure, writing this out in mathematics.

`$(50N)/(0.004m^2) =(Force-out)/(2m^2) $`

by solving above equation we get

Force-out = 25000N, 500 times greater than input force.

Answer 2

25,000N of force will be ouputed
