What minimum force $F$ is needed so that drum A can transmit a clockwise torque of $500$

$(1+0\mathrm{.}1)N-m$ without slipping $($Figure $2)?$ The coefficient of friction, ${}_s,$ between A and the

belt is $0\mathrm{.}4+(0\mathrm{.}01).$ What minimum coefficient of static friction is needed between drum

$B$ and belt for no slipping? Use drum diameters: ${0\mathrm{.}5}^{*}{D}_A=D_B=[150+(5)].$
