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
