The belt drive from the previous problem has an angle of wrap on the small pulley of $\backslash (160^\{\backslash$circ$\}\backslash ).$ Adding an idler, as in the figure below, increases this to $\backslash (200^\{\backslash$circ$\}\backslash ).$ If the slack$-$side tension is the same in the two cases and if centrifugal force is negligible, by what percentage is the capacity of the belt drive increased by adding the idler when $\backslash (\backslash$mu$=0\mathrm{.}33\backslash )?$
