The answer is E
A 12,000-N car is raised using a hydraulic lift, which consists of a U-tube with arms of unequal areas, filled with oil with a density of 800 kg/m^3 and capped at both ends with tight-fitting pistons. The wider arm of the U-tube has a radius of 18.0 cm and the narrower arm has a radius of 5.00 cm. The car rests on the piston on the wider arm of the U-tube. The pistons are initially at...

A winch (Figure Q.15) with a handle 250 mm long and radius of 40 mm is used to support a weight of 3300 N via a light, inextensible string. Turning the handle moves the weight along a straight line. Frictional losses in the winch result in it being only 40% efficient. The mechanical advantage of the system is: a) 16 b) 10 c) 6.3 d) 3.8 e) 2.5. 40 mm 250 mm Figure Q.15 Weight
