Which of the following types of soil is transported by gravitational forces?
In soil Mechanics Water Content (w) = Weight of water/weight of Soil.
take 0.9 Kg of dry Soil and add water about 1 liter (in volume) which is about 1Kg in weight.
Then the water content of mixture = 1/0.9 = 1.11 = 111%
which is greater than 100%,
Mud or slurry tends to have water content more than 100%.
Which of the following types of soil is transported by gravitational forces?
Total number of stress components at a point within a soil mass loaded at its boundary is
Correct Answer : c
Explanation : Considering a cube will give us 6 stresses till where it’s easy to get. And rest counting as 3 shear stresses along each plane in each direction will give total 9 stresses.
The submerged density of soil in terms of unit weight of watergw, specific gravity G and Voids
ratio e is given by the expression
A soil has a bulk density of 22 kN/m^{3} and water content 10%. The dry density of soil is
If the voids of a soil mass are full of air only, the soil is termed as
Correct Answer : c
Explanation : The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids. The void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction. Void ratio and porosity differ only in the denominator.
If the volume of voids is equal to the volume of solids in a soil mass, then the values of porosity and voids ratio respectively are
When the degree of saturation is zero, the soil mass under consideration represents
In a liquid limit test, the moisture content at 10 blows was 70% and that at 100 blows was 20%. The liquid limit of the soil, is
The liquid limit of the soil is 65 %
Let N be the number of blows and w be the water content at N blows.
Liquid limit = w × (N/25)⁰°¹²¹
For 10 number of blows = w (l) = 70 (10/25)⁰°¹²¹ = 89.55 %
For 100 number of blows = 20 ( 100/25)⁰°¹²¹ = 23.65 %
So liquid limit is = 89.55 %  23.65 % ≈ 65 %
If the degree of saturated of a partially saturated soil is 60% then air content of the soil is
If the water content of a fully, saturated soil mass is 100%, then the voids ratio of the sample is
The ratio of the volume of voids to the volume of soil solids in a given soil mass, is known
Relative density of a compacted dense sand is approximately equal to
If the sand in  situ is in its densest state, then the relative density of sand is
Which of the following methods is most accurate for the determination of the water content of soil?
For proper field control which of the following methods is best suited for quick determination of water content of a soil mass?
The hydrometer method of sedimentation analysis differs from the pipette analysis mainly in
