(Wpts) The bent rod ABCD is supported by the beating at A and by the cable DE. Rod ABCD can slide freely in the y direction at the hearing, but the bearing prevents rotation about the x and z axes as well as preventing translation in the x and 2. directions. The moment vector of the applied couple - at B is parallel to the z axis and the 27 lb. applied force at C is straight down in the —y direction. a) By analyzing rod ABCD, determine the required force in cable DE to maintain equilibrium. b) Calculate the magnitude of the force P (which is parallel to z direction). 0) Find all the support reaction components (forces m couples) acting at A. 4 ft ; A; _ ‘ DE <1 44 2 lb flag-"H so ? . _ A; Md It ‘3.
