Chapter 8, Problem 8-55(choose chapter or problem)
The wheel weighs 20 lb and rests on a surface for which \(\mu_{\mathrm{B}}=0.2\). A cord wrapped around it is attached to the top of the 30-lb homogeneous block. If the coefficient of static friction at D is \(\mu_{\mathrm{D}}=0.3\), determine the smallest vertical force that can be applied tangentially to the wheel which will cause motion to impend.
