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 40 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 F = 100 N forces at points D and F. Determine the necessary cable forces T1 in N.
