Question

How much effort will be required on the small piston having cross sectional area 20 sq. cm to lift a load of 4000 N on large piston having cross sectional area 1 sq.m? Also calculate the pressure exerted on the small piston.

Answer 1

to calculate pressure

we have to,

$pressure \: = force \div area$

so,

4000÷20

= 200pa
