PROBLEM 10.12 The slender rod AB is attached to a collar A and rests on a small wheel at C . Neglecting the radius of the wheel and the effect of friction, derive an expression for the magnitude of the force Q required to maintain the equilibrium of the rod. SOLUTION For : AAC tan AC a θ = ( ) tan A yA C a =− 2 cos A a y δ δθ For : CC B sin BC l A C = sin tan la = sin tan B yB C l a == 2 cos cos B a yl
