A homogeneous, 1.2 m wide, 2.4 m long rectangular gate weighing 3.6 kN is held in place by ahorizontal flexible cable as shown in figure. Water acts against the gate which is hinged at pointA.Friction in the hinge is negligible. Determine the tension in the cable. Please show the forces infree-body diagram.
