Pytel / Kiusalaas Engineering Mechanics: Statics, Fourth Edition Example Problem 2.66 The flexible shaft AB of the wrench is bent into a horizontal arc with a radius of 24 in. The two 20-lb forces, which are parallel to the z-axis, are applied to the handle CD, as shown. Determine the combined moment of the two 20-lb 24 n. radius rBD forces about the r-axis (the axis of the socket at point B). Гвс Solution: 1. Determine moment of forces about point B. Point B is the center of moment. 30°- - 6 in. --- 6 in. - Determine position vectors from point B to point C and point D; rBc, rBD We need coordinates of point C and D (point B is (0,0,0)) for that. 2.
