I need some assistance with these two Geotechnical Engineering Problems. D is 50 ft below the surface. The distributed load, q, is 200 psf. Please find the additional vertical stressinduced by the distributed load.50 ftAB30 ft80 ftEGiven Gs=2.75, calculate the zero-air-void unit weightfor a soil in Ib/ft3 at w=5%, 8%, 10%, 12%, and 15%.

Given: The specific gravity of soil is Gs=2.75. The expression for zero air void unit weight is given by, γzero air void=γww+1GS ... (1) Here, γw is the unit weight of water, w is the moisture content and GS is the specific gravity of soil. At 5% moisture content. Substitute the values in equation (1). γzero air void=62.40.05+12.75=150.9 lb/ft3 At 8% moisture content. Substitute the values in equation (1). γzero air void=62.40.08+12.75=140.7 lb/ft3At 10% moisture content. Substitute the values in equation (1). γzero air void=62.40.1+12.75=134.6 lb/ft3 At 12% moisture content. Substitute the values in equation (1). γzero air void=62.40.12+12.75=129.0 lb/ft3At 5% moisture content. Substitute the values in equation (1). γzero air void=62.40.05+12.75=121.5 lb/ft3 Therefore, the zero air void unit weight at different moisture content is tabulated below. Moisture content (%) Zero-air-void unit weight lb/ft3 5 150.9 8 140.7 10 134.6 12 129 15 121.5
