The rectangular plate of Prob. 6/94 is repeated here. The cables at A and B are now attached to a 50-lb trolley which is constrained to move in the horizontal guide. If the cable at A suddenly breaks, calculate the tension T_B in the cable at B an instant after the break occurs and the acceleration a_T of the trolley in the guide. Neglect friction and the mass of the trolley wheels.
