The tension in cable CD is T=455 lb. Consider the force which this cable exerts on point C and determine its moment about point O Assume a = 11 ft, b=4ft, c-7 ft. d=9ft, e=11 ft. C d C

Using the principles to be developed in Chapter 3 on equilibrium, one can determine that the tension in cable AB is 289.8 N. Determine the moment about the x-axis of this tension force acting on point A. Compare your result with the moment of the weight W of the 25- kg uniform plate about the x-axis. What is the moment of the tension force acting at A about the line OB? 0.38 m Mx = Answers: 0.57 m i -74.047 (Mx)w= MOB -63.853 0 A 0.51 m W 25 kg 23⁰ 0.92 m N-m N-m N•m

If the tension in the rope is 400 lb, what is the magnitude of the y component of the support force reaction at point A? Z A A X B (4, 9, 9) ft C (7, 11, 0)ft
