Question
For questions 1-4, assume there is a 3-meter-deep soil layer (measured in the slope-normal direction) with a density of 1600 kg/m³, cohesion of 18 kPa, and a friction angle of 25 degrees. The potential failure plane is located at the soil-bedrock interface, is parallel to the surface, and has a slope of 35 degrees. As usual, assume the acceleration due to gravity is 9.8 m/s², and the density of water is 1000 kg/m³.
