PROBLEM 10.12 The slender rod ABis attached to a collar Aand 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 Qrequired to maintain the equilibrium of the rod. SOLUTION For :AAC′∆tanACaθ′=( )tanAyACa′=−2cosAayδδθFor :CC B′∆sinBClA C′′=−sintanla=−sintanByBCla′==−2coscosBayl
