Problem 1 (30 points) The 9-ft steel beam weighs 280 lb and is hoisted from rest where the tension in each of the cables is 140 lb. If the hoisting drums are given initial angular acceleration ai= 4 rad/sec2 and a2 = 6 rad/sec?. (The beam may be treated as a slender bar, 7 = 1 - ml.) 12 Find: (a) The angular acceleration (CAB) of the beam (b) The acceleration of the center of mass (ag) of the beam (c) Tension TA and TB in the cables. 15" 15" 021 0.2 TE 3 3' 3 A UB с
