The block brake consists of a pin-connected
Chapter 8, Problem 8-8(choose chapter or problem)
The block brake consists of a pin-connected lever and friction block at B. The coefficient of static friction between the wheel and the lever is \(\mu_{\mathrm{s}}=0.3\), and a torque of 5 N\(\cdot\) m is applied to the wheel. Determine if the brake can hold the wheel stationary when the force applied to the lever is (a) P = 30 N, (b) P = 70 N.
