An external pressure applied to an enclosed fluid in a hydraulic lift. piston 1 has a radius that is 1/200 the radius of piston 2 (r1 = r2/200). if the bottom of both pistons start from the same vertical height, how much force needs to by applied to the first piston in order to begin lifting a weight of 20,000 n positioned atop the second piston?
Answers: 2
= radius of piston 1 
= radius of piston 2
= Force applied on piston 1 
= Force applied on piston 2 = Weight being lifted = 20000 N
