Question

A rectangular block of rock rests on a planar surface as shown in the following figure sketched in scale. The unit weight of the rock block is 26 kN/m^3, and its base has estimated strength parameters of 48kPa and a friction angle of 31 degrees. A. Estimate it's factor of safety against sliding. B. What is the factor of safety against toppling? C. If water were to fill the crack at the base of the block, how would that affect the factor of safety that you calculated in parts A. and B. ? Problem 1. A rectangular block of rock rests on a planar surface as shown in the following figure sketched in scale.
