1.What is the effective stress 25 feet deep if the specific weight of the dry soil (dry unit weight) is 120 pcf and the water table is 12 feet deep?
2.A 110 cm^3 sample of wet soil has a mass of 106 g and a degree saturation of 100%. When oven-dried, the mass is 81 g. Determine the 1) water content, 2) specific gravity, 3) void ratio, and unit dry weight of soil particles.
