Consider the cross-section of the gravity concrete dam shown below. Check its stability against overturning about the point O. The specific weights of water and concrete are 9.81kN/m3
and 23.54 kN/m3, respectively. Take into consideration the unit length of the dam and assume that the bottom is impervious (neglect the buoyancy due to the water at foundation).
