A lever such as that shown in Fig. 6-35 can be used to lift objects we might not otherwise be able to lift. Show that the ratio of output force, Fo, to input force, F1, is related to the lengths, l1and lo from the pivot point by Fo/F1 = l1/lo (ignoring friction and the mass of the lever), given that the work output equals work input.
