In a hydraulic lift the radii of the pistons are 1.25 cm and10.0 cm. A car weighing 16.5 KN is to be lifted by the force of the larger piston.
a) what force must be applied to the small piston?
b) when the small piston is pushed 30.0cm, how far is the carlifted?
c) find the mechanical advantage of the lift which is the ratio ofthe large force to the small force?
