A 25 m high concrete dam having trapezoidal section has top width 2m and bottom width 16m. The base of dam exposed to water has a slope of 1:10. on the reservoir side water stands up to top. Assume weight of concrete 2400 kg/m3 coefficient of friction 0.75. allowable shear stress 5kg/cm2. Consider weight of dam, water pressure and uplift pressure and check the stability of dam.
