... Stress and Friction 4. Consider a block of vesicular basalt that is 3 m long in each x, y, and z directions. The block is sitting on a rough horizontal surface (on the z-plane) with a coefficient of friction, f =0.4. Assuming 10% porosity, use an appropriate density, ρ, to answer the following: (a) ...
