A block of weight W is suspended by two cords, AC and BC, shown, and forces P (in the x direc) and Q (in the z dires) are exerted at C. Find the weight W of the block, and the fensions TAC and TBC in the two cords.

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
