In a hydaulic lift the radius of the pistons are 1.75cm and 17.5cm. A car weighing 19.6kN is to be lifted by the force of the large piston.
A) find the mechanical advantage of the lift (the ratio of the foce if the large piston to that of the small piston)?
B) what force must be applied to the small piston?
C) when the small piston is pushed 10.0m, how far is the car lifted?
