Question 1

The Rankine constant in Rankin’s formula is

Question 2

Consider a partially saturated soil sample in which

units, u_a= 7 units,(Pore air pressure)

u_w= 4 units (Pore water pressure) and x = 0.6. (saturation parameter) symbols have their usual meaning.

Find the value of effective stress for such soil sample.

Question 3

A horizontal shaft AB 15 m in length is fixed at ends When viewed from its left end axial couple of 30 kNm clockwise and 45 kNm anticlockwise act at 6 m anf 12 m from left end respectively. Fixed end couple at end A and B are respectively:

Question 4

For a normally consolidated clay soil, the following experimental dates are given:

If relation between k and e is given as

Correct value of n is:

Question 5

A soil deposit consists of a silt layer sandwiched between the fine sand layer at bottom and clay layer at top. Permeability of silt layer is 10 times the permeability of the clay layer and 1/10 of the permeability of the sand layer. Thickness of the silt layer is twice the thickness of the sand layer and 2/3 of the thickness of the clay layer. If the permeability of silt layer is 10 x 10^-5 cm/s then the equivalent horizontal permeability of the deposit is

Question 6

If the area of cross section of a circular beam is made four times, keeping load, length, support conditions and material of the beam unchanged, then the quantities (List -I) will change through different factors (List-II). Match the List -I with List-II and select the correct answer using the codes given below the lists:
