A natural slope consists of a homogeneous clay loam (CL) material. The cohesive strength (c) of the soil is 250 lbs/ft^2 and the angle of internal friction (theta) is 26 degrees. The unit weight (Ysat) of the soil is 112 lbs/ft^3. Compute the factor of safety for a rotational slide with a radius of 25.1 feet.
