The cylindrical roller shown in the figure is subjected to a moment (Ma=15kN-m). A rough belt (coefficient of static friction is 0.20) is wrapped around the roller and connected to a lever. Determine the value of F (in kN) such that the roller stays at res (strap brake). Use total length of the lever, I = 5m and a=180°. F Ma
