1. (10 pts.) The following data are given for a direct shear test conducted on dry sand: • Specimen dimensions: 63 mm x 63 mm x 25 mm (height) Normal stress: 105 kN/m² • Shear force at failure: 300 N a.) Determine the effective angle of friction. b.) For a normal stress of 180 kN/m2, what shear force is required to cause failure? c.) Considering the specimen in (b), what are the principal stresses, 0₁ and 03'? What is the inclination of the major principal plane with the horizontal?
