Question

A force of 40kgf is applied to the smaller piston of a hydraulic machine .Neglecting friction , find the force exerted on larger piston , if the diameters of the pistons are 10cm and 20cm respectively ?

Answer 1

Explanation:

Answer

Correct option is

A

5

We know that Pressure on both the Piston should be same,

∴Pressure on smaller Piston=Pressure on larger Piston

Area of smaller

Force on smaller

=

Area of larger

Force on larger

∴ Force on Larger=

Area of smaller

Force on smaller

×Area of larger

⇒

2.5×2.5×3.14

50

×12.5×12.5×3.14=1250kgf

Answer 2

Answer:

I hope this helps you
