The contour of a gate holding back water shown in the figure below is given by A

Question

The contour of a gate holding back water shown in the figure below is given by Ax = By2; where A = 10 and B = 3 m-1. The gate is held in equilibrium by a horizontal restraining force. The extent of the gate normal to the plane of the paper is 7 m. The gate is pivoted about the point O and the water depth is 1.8m. Find the restraining force necessary to hold the gate in equilibrium (i.e. the horizontal component of the hydrostatic force by the water acting on the gate.) 430 kN 133 kN 234 kN 111 kN

Explanation / Answer

It's C 234KN
