Fluid force on vertical plate: Determine the total force on the vertical plate that holds backwater (forces on plate are in equilibrium, and the plate is stationary) stored in a

large rectangular tank at a depth from 0 to 20 meters, as indicated in the Figure 1 below. Consider the plate is held in place by pins at the A and B positions. The width of the plate (distance into the page) is 50 meters. Provide the answer in metric units (Newtons).
