Geotechnical Engineering Exam 1 || with Accurate Answers 100%
Water content, w correct answers Ww/Ws (0 to 200%) Degree of Saturation, S correct answers Vw/Vv (0 to 100%) Unit Weight, gamma correct answers W/V (62.4 pcf or 9.81 kN/m3 for water) Mass Density, rho correct answers M/V = gamma/gravity (1000 kg/m3 for water) Total (wet) Unit Weight correct answers Wt/Vt = (Ws + Ww)/(Vs + Vv) = (1+w)*(dry unit weight) =Gs(1+w)(unit weight of water)/(1+e) Dry Unit Weight, gamma d correct answers Ws/V (60 to 125 pcf) Saturated Unit Weight, gamma sat correct answers (Ws + Ww)/V , Vair = 0 (90 to 140 pcf) ((Gs + e)/(1+e)) *(Unit Weight of water) Specific Gravity of Solids, Gs correct answers Ws/Vs * 1/unit weight of water (2.6 to 2.8) Void Ratio, e correct answers Vv/Vs (0.2 to 5.0) n/(1-n) = (Gs*(unit weight water) / Unit Weight dry) -1 Porosity, n correct answers Vv/V (0.2 to 0.9) e/(1+e) Gs*w = correct answers S*e Fines correct answers Smaller than the #4 sieve Coarse correct answers Everything retained on the #4 sieve % finer than d2 = correct answers 100 * (wpan + w4 + w3)/Wt Best shape of soils for good strength? correct answers Angular!! Roughest, sharpest, best shear strength Terminal Velocity, vs correct answers Effective depth / elapsed time Gradation curve correct answers Grain size (x axis), percent passing or percent finer (y)
