Solve Prob. 1 at the instant θ = 60°.

Prbolem

The forked rod is used to move the smooth 2-lb particle around the horizontal path in the shape of a limagon, r = (2 + cos θ) ft. If at all times  determine the force which the rod exerts on the particle at the instant θ = 90°. The fork and path contact the particle on only one side.
