Question: problem 03090 hinged quartercircular gate a 45mlong quartercircular gate...

Question details

Problem 03.090 - Hinged quarter-circular gate A 4.5-m-long quarter-circular gate of radius 3 m and of negligible weight is hinged about its upper edge A as shown in the figure. The te controls the flow of water over the ledge at B, where the gate is pressed by a spring. Determine the minimum spring force ed to keep the gate closed when the water level rises to A at the upper edge of the gate. Take the density of water to be 1000 kg/m3 The minimum spring force required to keep the gate closed is kN
