PROBLEM 10.48 Denoting by s µ the coefficient of static friction between collar C and the vertical rod, derive an expression for the magnitude of the largest couple M for which equilibrium is maintained in the position shown. Explain what happens if tan s θ . SOLUTION Member BC : Have cos B xl = sin B δ θδθ =− (1) and sin C yl = cos C = (2) Member AB : Have 1 2 B x l δφ = Substituting from Equation (1), 1 sin 2 ll −= or 2sin φθ = − (3) Free body of rod BC For max , M motion of collar C impends upward
