A 150 lb man stands on a 60 lb bar to which the cable is tied at B. The cable passes over two fixed pegs with coefficient of frictions as indicated. You may treat the cable the same as you would treat a flexible flat belt. assume the normal force exerted by the man in the bar acts downward through point A. Find the smallest force the man can exert on the cable if the bar is to remain horizontal.
