Let the dam material have specific gravity SG. The width of the dam is (b). Assume no seepage of water under the dam. Find an analytic relation between SG and the critical angle (B) for which the dam will just tip over to the right. Use your relation to compute for the special case SG =2.4 for concrete).(Ans. Cos²ß = 3+SG . B= 64.5°)
