13-106. The forked rod is used to move the smooth 2-lb particle around the horizontal path in the shape of a limaçon, r = (2+ cos 0) ft. If at all times = 0.5 rad/s, determine the force which the rod exerts on the particle at the instant =60°. The fork and path contact the particle on only one side. Ans: N=0.0493 lbf in +n, P = 0.0108 lbf in -0 0 = 60° -3 ft-
