PROBLEM 4.91
Two transmission belts pass over a double-
sheaved pulley that is attached to an axe
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.
