Find load with jack and piston

  1. Dec 2, 2005 #1
    A hydraulic jack has a pump piston of diameter 0.650cm, and a load piston of 4.40cm. Find the load which can be lifted if a force of 500.N is exerted on the pump piston.

    Would you use the equation Fd=F(2)d(2)?
    So (0.00650m)(500.N)=F(.0440m)

    No. The hydrostatic principle here is that the pressure is the same for both pistons. (How do force, pressure, and area relate to each other?)
