5-73. The windlass is subjected to a load of 150 Ib. Determine the horizontal force P needed to hold the handle in the position shown, and the components of reaction at the ball-and-socket joint A and the smooth journal bearing B. The bearing at B is in proper alignment and exerts only force reactions on the windlass. 5-15. Member AB is supported by a cable BC and at ‘A by a square rod which fits loosely through the square hole at the end joint of the member as shown. Determine the components of reaction at A and the tension in the cable needed to hold the 800-Ib cylinder in equilibrium. Ans EF, 30; ‘Ans =F.
