99. Pick up the correct statement from the following :
A. Failure plane carries maximum shear stress
B. Failure plane does not carry maximum shear stress
C. Failure plane carries shear stress equal to maximum shear stress
D. None of these.

100. The angle between the directions of the failure and the major principal plane, is equal to
A. 900 + effective angle of shearing resistance
B. 90? + half of the angle of shearing resistance
C. 45? - half of the angle of shearing resistance
D. 45? + half of the angle of shearing resistance.

101.  If drainage is permitted throughout the test, during the application of both normal, and shear stresses so that full consolidation occurs and no excess pore pressure is set up at any stage of the test, is known as
A. quick test
B. drained test
C. consolidated undrained test
D. none of these.

102. When drainage is permitted under initially applied normal stress only and full primarily consolidation is allowed to take place, the test is known as
A. quick test
B. drained test
C. consolidated undrained test
D. none of these.

103.  A direct shear test possesses the following disadvantage:
A. A relatively thin thickness of sample permits quick drainage
B. A relatively thin thickness of sample permits quick dissipation of pore pressure developed during the test
C. As the test progresses the area under shear, gradually changes
D. none of these.

104.  A triaxial shear test is prefered to direct shear test, because
A. it can be performed under all three driange conditions with complete control
B. precise measurement of pore pressure and change in volume during test, is not possible
C. stress distribution on the failure plane, is non uniform
D. none of these.

105. For shear strength, triaxial shear test is suitable because
A. it can be performed under all three drainage conditions
B. precise measurement of the pore pressure and volume change during the test is possible
C. stress distribution on the failure plane, is uniform
D. all the above.
