Hydropower Engineering past question

Calculate the forces and the principle stress and the shear stress at the toe and heel of the gravity dam section shown below. Check the dam against sliding, crushing, overturning and tension. Do not consider the forces other than self-weight, hydrostatic pressure and uplift pressure. Assume allowable compressive stress for the material of the foundation is 50 kg/cm², allowable crushing stress for the material of the dam body is 10.5 kg/cm², friction coefficient is 0.70 and uplift coefficient is 0.45.
