The angle of internal friction of a cohesive soil which was tested using a tri-axial shear apparatus is equal to 26.57°. Failure occurred when the shearing stress is 250 kPa and the normal stress is 480 kPa. Determine the maximum principal stress at failure, in kPa. Round off to two decimal places. (ANS: 884.55)
