Name :

If two hydraulic lift have the same small area the first one can lift up to 10 Kg while the second one can lift up to 100 kg which hydraulic press has a higher mechanical advantage.

As an engineer if you were asked to design a dentist chair that can lift up to a 100 kg person if the small piston was of area 2 cm2 and the force applied on it is 10 N then the area of the big piston must be

If the ratio between the small radius of a hydraulic press and the large radius is 1 : 4 then the ratio between the force applied on small piston to the force produced by a large piston is

A mechanical engineer used a hydraulic press of advantage = 2 , to lift a car if the small piston moved with a velocity 20 m/s vertically upward then the large piston moves with a velocity
