Question

Prove hydroulic machineis force multiplier

Answer 1

Answer:

As you know hydraulic machines have 2 pistons: Larger and Smaller. It works on the principle of Pascal's law which states:

F2/F1 = A2/A1

Suppose two pistons have an area of 10 cm sq. and 20 cm sq. Now, lets put a body on the smaller piston having an area of 10 cm sq. which will exert a force of 100 N.

F2/100 = 20/10

F2 = 200 N

This shows that if we put a force of 100 N on smaller piston, we will get a force of 200N on the other piston. Hence, it proves that hydraulic machines act as force multipliers.

I hope this helps.
