- Based on Problem 5-87 from the textbook. Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is tramsitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components of reaciotn at the journal bearing C and thrust bearing D. The bearings are in proper alignment and exrt only force reactions on the shaft.

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.arrow_forwardI Draw the free-body diagrams and write the differential equations of motion for the two masses in terms of x₁ and .x2. b.
