QUESTION 4 (20 marks) Following information is reported on the basis of a direct shear test conducted on dry sand; Specimen dimension: 50mm x 50mm x X mm Gs=2.7 . Normal stress: 150+X kPa Angle of friction: 32° . a) Determine the shear force required to cause failure (5 marks) b) What was the mass of the sample if the initial void ratio of the sample is 0.64. (10 marks) c) A second test was conducted on the same sand at the same void ratio under the normal stress of 250+X kPa. What is the shear stress required to cause the failure? (5 marks)
