Question

Prob. A 20-b uniform disk is placed in contact with an inclined surface and a constant 7.5 lb-ft couple M is applied as shown. The weight of the link AB is negligible. Knowing that the coefficient of kinetic friction at D is 0.4, determine (a) the angular acceleration of the disk, (b) the force in the link AB. a rough horizontal surface and end B supported by a smooth vertical surface. Knowing that the deceleration of the truck is 12 ft/s2, determine (a) the reactions at ends A and B, (b) the minimum required coefficient of static friction at end A. 5 ft 60°
