A uniform disk of mass m=20 lb and radius r=9 inches is placed in contact with an inclined surface and a constant couple M = 7.5 lb.ft is applied as shown (see attachment). The weight of link AB is negligible. Knowing that theta = 30 degree and the coefficient of kinetic friction at D is k = 0.4, determine the angular acceleration of the disc and the force in the link AB.© BrainMass Inc. brainmass.com March 4, 2021, 8:38 pm ad1c9bdddf
