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?
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?
