(25 points) Problem 15.4 using Rankine. When calculating F.S. for overturning, ignore the contribution of Pp. When calculating FS. for sliding include Pp in your calculations, but decrease the effective friction angle and effective cohesion by 2/3 i.e. c'used- (2/3)c'soil (25 points) Using Coulomb's active pressure, recalculate the factors of safety with respect to overturning and sliding for problem 15.4. Assume d 2/3 f. In both analyses ignore the contribution of Pp. When calculating F.S. for sliding, decrease the effective friction angle and effective cohesion by 2/3.
