Question

A hydraulic lever has input surface area 2 m^2, and output surface area 10 m^2, if the input force is 5 N, then what is the output force?

(a) 1 N

(b) 2 N

(c) 5 N

(d) 10 N

This question was addressed to me in class test.

My doubt stems from Measurement of Pressure in section Temperature and Pressure of Basic Chemical Engineering

Answer 1

Correct answer is (a) 1 N

To explain: Hydraulic lever works on the Pascal’s principle, => F1A1 = F2A2, => 5*2 = F2*10, => F2 = 1 N.
