Name: _____________________________ Section: ____________ Problem #1 (20 points): The elbow AB is attached to the smooth square rod at A with a loose fitting collar, and is supported by cable BC. Note that the collar allows motion along the pole only; motion in other directions is prevented. Find the tension in the cable (T BC ) and ALL components of the reaction at A (A x , A y , M Ax , M Ay , M Az ). The force F = -300 k lbs.

Name: _____________________________ Section: ____________ Problem #2 (20 points): The structure ACD is constrained by a fixed support at D and a cable AB that is attached to the ground at B. Shaft CD lies along the z-axis, and arm AC is parallel to the y-axis. Coordinates for the points are: A = (0,2,2), B = (1,3,0), C = (0,0,2), and D = (0,0,0). The tension in AB is known to be 24 kN. (c) Express the force at A, due to the tension in AB, as a Cartesian vector (i.e. with x, y, and z components). (d) Calculate ALL components of the reaction at D. CLEARLY show the directions of all components on a FBD of ACD. x y z
Name: _____________________________ Section: ____________ Problem #3 (20 points): The vertical mast AB is constrained by two cables BC and BD and by a ball-and-socket joint at A.
