Question

32. A force of 20kgf is applied to the smaller piston of a hydraulic machine find
the force exerted on the large piston if diameters of piston being 10cm and
20cm respectively *
Alas​

Answer 1

We know that the pressure on both the piston should be same.

Pressureonsmallerpiston=Pressure on larger piston

That is,

Force on smaller/Area of smaller = Force on larger/Area of larger

Therefore,

Forceonlarger= Area of smaller/Force on smaller × Area of larger

⟹ 50/2.5 × 2.5 × 3.14 × 12.5 × 12.5 × 3.14 = 1250kgf
