A slender bar of length L = 400 mm is held in equilibrium, with one end touching a frictionless wall and the other end attached to a wire of length S = 600 mm as illustrated. Knowing that the weight of the bar is 147 N (which acts at the mid-length of the bar), determine: a. the distance h. b. the tension in the wire. c. the reaction at B. C. В

y 150 mm 100 mm TB 200 mm D Tc T'c 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.
