97) If the shearing stress is zero on two planes, then the angle between the two planes is

45°

90°

135°

225°

Answer is:

90°

98) In the triaxial compression test, the application of additional axial stress (i.e. deviator stress) on the soil specimen produces shear stress on

horizontal plane only

vertical plane only

both horizontal and vertical planes

all planes except horizontal and vertical planes

Answer is:

all planes except horizontal and vertical planes

99) In a triaxial compression test when drainage is allowed during the first stage (i. e. application of cell pressure) only and not during the second stage (i.e. application of deviator stress at constant cell pressure), the test is known as

consolidated drained test

consolidated undrained test

unconsolidated drained test

unconsolidated undrained test

Answer is:

consolidated undrained test
