Shear strength of sandy soil is constituted basically with which of the following components.
1) The structural resistance to displacement of the soil because of Interlocking of the particles.
2) The frictional resistance to displacement of the soil because of interlocking of the particles.
3) Cohesion or adhesion between the surfaces of the soil particles.
Question 4

Question 7
There is a 20 m high dam constructed on an impermeable foundation. The coefficient of permeability of soil used for the construction of dam in horizontal and vertical direction is 4 .8 × 10–8 m/s and 1.6 × 10–8 m/s respectively. The water level on the reservoir side is 18 m from the base of dam but the downstream side is dry. Flow net shows that there are 4 flow channels & 18 equipotential drops. The quantity of seepage per unit length in m3/sec through the dam is?
Question 8
Approximate ratio of capillary rise in two soils of same void ratio having their effective sizes as 0.2 mm and 0.1 mm respectively will be?
Assume the value of C for the soils as 1 cm2 and 0.8 cm2 respectively.
void ratio= 1

As per the Stokes law the terminal velocity of a particle is
Question 10
A 2m × 2m footing exists at a depth of 1m below ground level in sandy soil. Calculate the increase in effective stress at 3m below the footing if the load on the column is 2000 kN. Assume 2:1 load distribution.
