The 80 lb boy stands on the beam and pulls on the rope with a force of 40 lb. (4)D=0.4 and (4) D = 0.35 between his shoes and the beam. The beam has a weight of 0.641 lb/in all along it's length. Neglect the thickness of the beam. Also neglect the size of the pulleys (i.e. assume the rope acts at points F & G). a) Is the boy stationary or slipping? b) Determine the beam support reactions at A and B. 13 12 56 E Aft

The heavy box of statics knowledge hangs from 3 ropes. Ropes AD and BD are equal length and attach to points on the x-axis. Attachment C is in the xy plane and is closer to A than B. Suppose rope CD is lengthened until point D lies in the xz plane. Which of the following statements accurately describes the resulting tensions in the ropes? y O TBD > TAD and TcD = 0 O TBD < TAD and TCD = 0 O TBD = TAD = TCD O TBD = TAD and TCD = 0 %3D Please explain your answer in the box below. B.
