A bent lever (Fig. 43) has its arms at = 1 5 inches, BC = 6 pivoted at C. AC A force P of 35 Ib. is applied at A inches. at 1 5 to the horizontal, and another Q is applied Find the magnitude at B at 20 to the vertical. of Q and the magnitude and direction of the reaction at C required to balance P and Q. 5. 90 and ^p is A body weighing 24 Ib. is kept at rest incline which makes 40 with the horizontal by a force P which is parallel to the plane (Fig. 44). Assume that the reaction of the plane is at 90 to its surface, and find P.
