A consolidated-undrained tri-axial test was conducted on a normally consolidated clay sample and the results are as follows: Chamber confining pressure 112 kPa, Deviator stress at failure = 90 kPa, Pore Water Pressure 67 kPa. These results were used to determine the drained friction angle of the soil. Compute the deviator stress (kPa) at failure when the drained test was conducted with the chamber confining pressure changed to 156 kPa. Round off to two decimal places.

Question
A consolidated-undrained tri-axial test was conducted on a normally consolidated clay sample and the results are as follows:
Chamber confining pressure =
112 kPa, Deviator stress at failure = 90 kPa, Pore Water Pressure = 67 kPa.
These results were used to determine the drained friction angle of the soil. Compute the deviator stress (kPa) at failure when the
drained test was conducted with the chamber confining pressure changed to 156 kPa.
Round off to two decimal places.
