Compute the factor of safety for overturning(about the footing toe) and sliding for the retaining wall shown below and determine if the wall is adequately designed for stability.
The wall stem and footing are each 12 inch thick, constructed from reinforced concrete that weighs 150 pounds per square feet. The retained soil weighs 120 pounds per square feet, and the soil-concrete coefficient of friction, μ is 0.4. The factor of safety against overturning must be greater than 1.5, and for sliding it must be greater than 1.2.
Hint: There are three weights and three moments that contribute to the stability.
