Q3. A sand sample of 35 cm2 cross sectional area and 20 cm long was tested in a constant head permeameter. Under a head of 60 cm, the discharge was 120 ml in 6 min. The dry weight of sand used for the test was 1120 gm, and Gs = 2.68. Determine (a) the hydraulic conductivity in cm/sec, (b) the discharge velocity, and (c) the seepage velocity.

Assignment 01 TOT Mechanical Properties of Materials 1. A tensile test specimen has a gage length = 50 mm and its cross-sectional area = 100 mm. The specimen yields at 48,000 N, and the corresponding gage length - 50.23 mm. This is the 0.2 ent yield point. The maximum load of 87,000 N is reached at a gage length 64.2 mm. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) If fracture occurs at a gage...
