Required information

The $17-$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. The value of ${}_s=0\mathrm{.}30$ between the cable and the drum.

Determine the largest counterclockwise couple $M_0$ that can be applied to the drum if slipping is not to occur.

The largest counterclockwise couple that can be applied to the drum if slipping is not to occur is $134\mathrm{.}24*$ ib$-$in$.$
