Question 1
Consider the following statements:
1). Poorly graded or uniform sands compact to low dry unit weights.
2). Heavy clays with high plasticity have very low maximum dry weight.
3). In clay soils, the maximum dry weight tends to decreases as plasticity increases.
Which of these statements is/ are correct?
1). Poorly graded or uniform sands compact to low dry unit weights.
2). Heavy clays with high plasticity have very low maximum dry weight.
3). In clay soils, the maximum dry weight tends to decreases as plasticity increases.
Which of these statements is/ are correct?
Question 2
The ratio of moment of inertia of the composite beam when the whole section is transformed into wood to when the whole section is transformed into steel is
(Here m is the modular ratio of steel and wood)
Question 3
Assertion (A): For a given soil, the optimum moisture content increases with the increase in compactive effort.
Reason (R): Presence of water facilitates rearrangement of soil grains under given compaction effort, thereby reducing the voids in between the soil grains.
Question 4
A simply supported beam of width 100 mm, depth 150 mm and a span of 2 m carries a point load of 10kN at the mid span. It is also subjected to an axial compressive load of 10 kN. What is the maximum tensile stress anywhere in the beam (in N/mm2)?
Question 5
Which of the following pairs is not correct?
a) Low plastic soil : Ip < 7
b) Medium stiff soil: IL = 0.25 – 0.5
c) Very soft soil: IC : 0.25 – 0.15
d) Loose soil : Dr = 15 – 35
Question 6
The shear stress distribution for a circular section of diameter ‘d’ under the action of shear force ‘S’ is correctly shown by:
Question 7
In kaolinite crystal, the layers are held by which of the following bonds?
Question 8
A symmetrical I-beam of flange width 100mm, web width 10mm, flange depth 10mm and web depth 150 mm is subjected to a shear force of 1000 N. What is the ratio of the shear stress at the top of the web and at the bottom of the top flange?
Question 9
Consider the following effects as indicative of complete saturation of a soil sample:
1) Pore water pressure is positive.
2) Volume of water to volume of voids is equal to 1.
3) Relative density is equal to 1.
Which of the above statements are correct?
1) Pore water pressure is positive.
2) Volume of water to volume of voids is equal to 1.
3) Relative density is equal to 1.
Which of the above statements are correct?
Question 10
Assertion(A): A circular cantilever beam subjected to a twisting moment and a bending moment will have a state of zero stress at the centre.
Reason(R): A bending moment caused by transverse loading will cause transverse shear.
