Which of the force systems in (b) through (f) are equivalent to the 21-kN force in (a)?

3.22 Calculate the moment of the 550-lb force about point 0 shown without using Varignon's theorem. Make a similar calculation using the theorem, resolving the force into its X and Y components at point A. 550 lb

For the frame shown, determine: Horizontal Component of the force at B,C,D and Vertical component of the force at B,C,D in lb. Need only a handwritten solution only (not a typed one).

The bent bar as shown below is supported by a cable AE, a ball-and-socke joint at O, and a journal (slider) bearing at D. At the journal bearing D, the mome support reactions and the force support reaction along y-axis are zero. The 2-kip force and the 6 kip-ft couple-moment are parallel to z-axis and applied at point B Determine the tension in the cable AE and the support reactions at O and D. A 4 ft X MEST Z 6 kip-ft 2 ft B 2ft 2 kips 3 ft [ 1 kip = Lo = 1000 lb. 1 E 14 ft y
