3. A homogeneous, 2 -m-wide, 8-m-long rectangular gate weighing 3kN is held in place br a horizontal flesible cable as shown in Fig. 2. The gate is hinged at point A. Friction in the hinge is negligible. Ignore the self-weight of the gate. Determine: a. the hydrostatic force [F1] exerted on the ate, b. the location of the pressure center (i.e., Fu) on the gate, and c. the tension in the cable. [6+6+4=16] Given: Specific weight of water, w=9.81kN/m2
