Session time: sunday 2:30 pm 4:30 pm location: e130 howe-russel. Date: 10/15/2017: determine the moment of each of the three forces about point b, two couples act on the frame. If the resultant couple moment is to be zero. determine the distance d between the 100 lb couple forces: the 455 n force on rod abc acts through line cf. If f lies on the xy plane, determine: moment of the force about e, moment of the force about axis be, the pipe assembly is secured on the wall by the two brackets. The collar is fixed to the rod ab, but is allowed to slide along rod cd. Neglect the size of the collars at d and b and the thickness of the boom, and compute the horizontal and vertical components of force at the pin a and the force in cable cb. The crane carry a crate mass of 40- slug suspended from a cable at b.
