The bar AB in figure "a" has weight W, length L, and is articulated at point B. End A is supported by a light thread, which passes through a smooth pulley, from which a block hangs at its other end. . Required: (a) Determine how much the block must weigh so that bar AB is in equilibrium. (b) Assuming that the block actually has the value calculated before, but instead of the bar being hinged at B, it only rests on a rough plane with coefficient μ= 0.7, as shown in figure "b". Is the bar balanced?
