The bottom hole in the dam is blocked by a flat rectangular shield with a width of -6 m. The water depth in the upstream h1 = 23 m, the depth in the downstream h2 = 11.5 m, the height of the bottom hole t = 17.25 m, the angle of inclination a = 40 °. The sewing can rotate around the axis, which is projected to point A. Determine the force T required to raise the shield.
