There is water on both the upstream $($right$)$ and downstream $($left$)$ sides of the dam body cross$-$section seen above. Answer the questions given in the options using the last three digits

a$)$ Calculate the hydrostatic forces and impact points on each unit

b$)$ Calculate the lifting force acting under the structure and its impact point

c$)$ Calculate the weight and center of gravity of the water structure

d$)$ Calculate the total shear resisting force, the total shear force and determine whether it is safe against slipping.

e$)$ Based on point i$,$ calculate the total anti$-$rotation moment, the total overturning moment and determine whether it is safe against overturning.
