1. Two tape spools are attached to an axle supported by bearings at A and D. Assume that the bearing at A does not exert any axial thrust. The radius of spool B is 1.5 in and the radius of spool C is 2 in. Knowing that TB= 20 lb., determine (a) the tension, Tc, and (b) the reactions at A and D. Ans: Tc = 15 lb, %3D %D A = 0î +14ĵ+4.5k Ib D=0f +6j+10.5k lb %3D
