- The combined moment of the two forces, each of magnitude P, about point A is zero. Determine the distance d that locates A.The figure shows one-half of a universal coupling known as the Hooke's joint. The coupling is acted on by the three couples shown: (a) the input couple consisting of forces of magnitude P, (b) the output couple C0, and (c) the couple formed by bearing reactions of magnitude R. If the resultant of these couples is zero, compute R and C0 for P=750lb.The couple acts on the handles of a steering mechanism. In the position shown, the moment applied by the couple about the z-axis is zero. Determine the distance b. Use F=150i90j+60kkN.
- Given that T=43kN and W=38kN, determine the magnitude and sense of the moments about point B of the following: (a) the force T; (b) the force W; and (c) forces T and W combined.The four forces shown act on the rollers of an in-line skate. Determine the equivalent force-couple system, with the force acting at O (the ankle joint of the skater).The two forces of magnitude F=30kN form a couple. Determine the corresponding couple-vector.
