Q.2) A plate is supported by a rope and two hinges as shown in figure. Assume that hinges do not exert couples on the plate, and the hinge at A does not exert a force on the plate in the direction of the hinge axis. If the plate is uniform with 50 kg mass, determine the tension in the 240 mm 240 mm гope. 400 mín 400 mm 200 mm! 200 mm B 480 mm
