You own a geotechnical engineering firm in NYC and your company has been hired by City College to conduct a slope stability analysis. Consider a 10.0 m-thick mass of regolith sitting on top of a bedrock surface with a slope of 14 degrees. Marshak is located at the top of this slope (and set back from the edge only 20 m). Upon an initial visit, you determine that the regolith is unsaturated (dry). You also estimate the following additional parameters for this Site: regolith cohesion = 1100 N/m^2 regolith angle of internal friction = 15° density of regolith = 2200 kg/m^3 (density of water = 1000 kg/m^3) What is the value for the Factor of Safety? Would you consider the slope currently stable? Explain your answer.
