Task 20 A concrete dam has the following dimensions: length b = 8m, height h1 = 4.8 m, top width a = 2m. Check the stability of the dam for overturning relative to point O by finding the holding and overturning moments if the water level in the upstream (WB) is h1, and in the downstream (MB) – h2 = 3.4 m. The angle of inclination of the rear wall to the horizon is 60 °.
Masonry density p = 2500 kg/m3. (h is perpendicular to the plane of the drawing.)
Indication. The center of gravity of the wall is found graphically.

The solution is made in the Word editor with a set of formulas. The task is performed as part of the control work on hydraulics. After payment, we guarantee to receive a file with this task. It is possible to perform according to your tasks.
