Textbook Question
Chapter 8.4, Problem 8.128P
The 10-lb bar AE is suspended by a cable that passes over a 5-in.-radius drum. Vertical motion of end E of the bar is prevented by the two stops shown. Knowing that μS = 0.30 between the cable and the drum, determine (a) the largest counterclockwise couple M0 that can be applied to the drum if slipping is not to occur, (b) the corresponding force exerted on end E of the bar.
