In a hudraulic lift, the radii of the pistons are 2.50 cm and 10.0 cm. A car weighing 10.0 kN is to be lifted by the force of the large piston. (a) what force must be applied to the small piston? (b) when the small piston is pushed in by 10.0 cm, how far is the car lifted? (c) Find the mechanical advantage of the lift, which is the ratio.
