The hydraulic oil in a car lift has a density of 8.29 x102 kg/m3. The weight of the input piston isnegligible. The radii of the input piston and output plunger are5.38 x 10-3 m and 0.136 m, respectively. What inputforce F is needed to support the 24800-N combined weightof a car and the output plunger, when (a) thebottom surfaces of the piston and plunger are at the same level,and (b) the bottom surface of the output plungeris 1.40 m above that of the input plunger?
(a) Number 38.8 Units N
(b) Number
Units N
