Beer, 9.a Ed, Excercise 4.92 Two drive belts pass over reels welded to a shaft supported by bearings at A and D. The reel at B has a radius of 30 mm, and the reel at C has a radius of 40 mm. Knowing that TB is 80 N and that the system rotates with a constant angular velocity, determine the reactions at A and D. Assume that the bearing at A exerts no axial thrust force and neglect the weights of the reels and the shaft.
