Consider the rectangular-triangular gate shown below. The gate is hinged along its 4-meter edge. The weight of the gate is negligible, and the specific weight of the water is ?water = 9.81 kN/m3.
(7 pts) Calculate the force of the water pressure exerted on the triangular portion of the gate.
(7 pts) Locate the center of pressure on the triangular portion of the gate (CP2) by calculating the distance b in Figure 2.
(7 pts) Calculate the force of the water pressure exerted on the rectangular portion of the gate.
(7 pts) Locate the center of pressure on the rectangular portion of the gate (CP1) by calculating the distance a in Figure 2.
(7 pts) Calculate the magnitude of the force Q required to keep the gate closed in the position shown.
(Extra Credit: 5 pts) Why are CP1 and CP2 located halfway along the 4-meter length of the gate?
