Solved: The coefficients of friction between the block and the rail are ms 5 0.30 and mk
Chapter 4, Problem 4.83(choose chapter or problem)
The coefficients of friction between the block and the rail are \(\mu_s = 0.30\) and \(\mu_k = 0.25\). Knowing that \(\theta = 65^{\circ}\), determine the smallest value of P required (a) to start the block up the rail, (b) to keep it from moving down.
