You are given a mohrs circle with 10 kPa (assume positve since geotech question) in compression for sigmaz and 2 kPa (+ counterclockwise) force for shear z. This force lies on a plane 15 degrees CW. Force sigma x is 9kPa(assume positive as well) in compression) and a -3 kPa for shear x. This force lies on an unkown plane. Draw a mohrs circle and solve for max shear forces.
