Solve Problem 4.91, assuming that the pulley rotates at a constant rate and that TB = 104
Question:
Solve Problem 4.91, assuming that the pulley rotates at a constant rate and that TB = 104 N, T′B = 84 N, TC = 175 N.
PROBLEM 4.91
Two transmission belts pass over a double-sheaved pulley that is attached to an axle supported by bearings at A and D. The radius of the inner sheave is 125 mm and the radius of the outer sheave is 250 mm. Knowing that when the system is at rest, the tension is 90 N in both portions of belt B and 150 N in both portions of belt C, determine the reactions at A and D. Assume that the bearing at D does not exert any axial thrust.
