a) For a direct shear test on a dry sand, the following are
given: - Specimen size: 75 mm × 75 mm × 30 mm (height) - Normal
stress at failure: 200 kPa - Shear stress at failure: 175 kPa For a
normal stress of 150 kPa, what shear force is required to cause
failure in this specimen? 10 b) For a normally consolidated clay,
given ϕ = 20o and ϕ′ = 28o . If a CU triaxial test is conducted
with the same soil with the all-around confining pressure of 140
kPa. What would be the pore water pressure at failure?
