A plain concrete wall (i.e., a wall with no steel reinforcement) rests on a secure foundation and serves as a small dam on a creek (see figure). The height of the wall is h = 6.0 ft and the thickness of the wall is t = 1.0 ft. Determine the maximum tensile and compressive stresses o*!and trt, respectively, at the base of the wall when the water level reaches the top {d = h). Assume plain concrete has weight density ye= 145 lb/ft . Determine the maximum permissible depth dnuxof the water if there is to be no tension in the concrete.
