(II) A lever such as that shown in Fig. 6-35 can be used
Chapter 17, Problem 7P(choose chapter or problem)
(II) A lever such as that shown in Fig. can be used to lift objects we might not otherwise be able to lift. Show that the ratio of output force, \(F_{0\), to input force,\(F_{1}\), is related to the lengths \(l_{1} \text { and } l_{O}\) from the pivot point by \(F_{O} / F_{I}=l_{I} / l_{O}\) (ignoring friction and the mass of the
lever), given that the work output equals work input.
