wo weights are hung over two frictionless pulleys that are connected by a wire rope to a 500 lb horizontal block that are in between and below them. The wire rope attached to the upper left end of the block and to the left pulley is at 45 degrees with the horizontal and the wire rope that connects the upper right end of the block to the right pulley is at 30 degrees with the horizontal. If the weight on the left pulley is 50 lb, fs = 0.30 and fk= 0.20 on the surface of block what weight W on the right pulley will cause the 500 lb block to just start moving to the right?
