The structure ABCD (shown below) is designed to support a finite mass hanging from a cable, DF, attached to the structure at point D. x=8m, y=6 m, and z-15 m. The structure is mounted to the ground by a hinge at B and a roller at C and is also supported by a horizontal cable, AE, attached to the wall. The mass of the object hanging from cable DF is 500 kg. The tension in the support cable AE is 1.000 × 10³ N. Determine the force in each member and the reaction forces. E D

In the figure, a nonuniform bar is suspended at rest in a horizontal position by two massless cords as shown in the figure here. One cord makes the angle 0 = 31.1° with the vertical; the other makes the angle p = 58.9° with the vertical. If the length L of the bar is 5.9 m, compute the distance x from the left end of the bar to its center of mass. L com
