(B) Total mass of soil sample to volume of soil solids
(C) Mass of soil solids to total volume of soil sample

(D) Mass of soil solids to volume of soil solids

82. Which of the following can be the unit of coefficient of permeability?
(A) cm/sec ൯ 14/0:
(C) cm/sec (D) cm/sec?

83. Which of the following is an incorrect statement as per Mohr’s strength theory?
(A) Critical failure shear depends upon soil properties and normal stress

(B) Ultimate shear strength of soil is determined by the stresses on the potential

failure plane

(C) When soil material is subjected to three dimensional principal stresses the failure

criterion is dependent on intermediate principal stress

(D) The plot of shear stress and normal stress corresponding to failure is called

strength envelope

overburden pressure and is completely consolidated under existing pressure is called as:
(A) Under consolidated ൯) Pre-consolidated
(C) Over consolidated (D) Normally consolidated

85. Which of the following is a correct statement?
