Question
The hand brake for a bicycle is shown. Portions DE and FG are free to rotate on
bolt A which is screwed into the frame BC of the bicycle. The brake is actuated
by a shielded cable where T1 is applied to point E and T2 is applied to point G.
A spring having 60 N compressive force is placed between points E and G so
that the brake stays open when it is not being used. Assume the change in the
spring's force is negligible when the brake is actuated to produce the forces P =
350 N at points D and F.
