Question: Blocks A and B are connected by a cable that passes over support C. Friction between the blocks and the inclined surfaces can be neglected.

Blocks A and B are connected by a cable that passes over support C. Friction between the blocks and the inclined surfaces can be neglected. Knowing that the coefficient of static friction between the rope and the support is 0.50, determine the range of values of WB for which equilibrium is maintained.
