Chapter 4, Problem 74P

Determine the location of the resultant force acting on the beam from point A. Draw a free body diagram of the beam with the resultant force and it's location clearly labeled. Make sure you include the reactions at the supports in your free body diagram. 800 N/m -3 m 500 N/m 3 m B

The forces P and Q act on the handles of the wrench. If P = 321b and Q = 36 lb, determine the combined moment of the two forces about the z-axis.

The combined moment of the three forces is zero about the axis a-a and the axis b-b. Determine the distances x0 and y0.

To lift the table without tilting, the combined moment of the four parallel forces must be zero about the x-axis and the y-axis (O is the center of the table). Determine the magnitude of the force F and the distance d.

The vertical post is secured by three cables. The cables are pretensioned so that the resultant of the cable forces F, Q, and P is directed along the z-axis. If F = 120 1b, find P and Q.

5 The compound bar is supported by a thrust bearing at A, a slider bearing at B, and the cable CD. Determine the tension in the cable and the magnitude of its moment about the x axis. D 2.8 ft ! 3.5 ft 3.5 ft 270 lb

The turnbuckle is tightened until the tension in cable AB, is T-3.2 kN. Calculate the magnitude of the moment about along OP line of the force Tacting on point A. 5 m A 3 m 2 m B 2 m

If the tension in the cable is F = 140 lb. determine the magnitude of the moment produced by this force with respect to the articulated axis CD of the panel

The design specifications for the attachment at A for this beam depend on the magnitude and location of the applied loads. Represent the resultant of the three forces and couple by a single force R at A and a couple moment. Take: M 25 kN .m ;a = 30 ; x = 1.6.m 4 kN 2 m -1.5 m- -0.8 m 2 kN 3 kN
