A consolidated undrained (CU) triaxial test was conducted on a normally consolidated clay sample with a confining stress of 100 kPa. The sample failed when the principal stress difference (deviator stress) was 80 kPa. The pore water pressure at failure was measured to be 60 kPa. Assume the cohesion intercepts c=c' = 0 kPa. a. Find the major and minor effective principal stresses at failure (sigma1f and sigma3f).
b. Determine the effective internal angle of friction (phi').
c. Determine the normal effective stress (sigma'f) and the shear stress (sigma’f) on the plane of failure.
d. Find the expected shear strength at failure if a direct shear test is conducted on the same clay which is subjected to an effective normal stress of 150 kPa.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
