Ques 27 General Aptitude

The figures I, II and III are parts of a sequence. Which one of the following options comes next in the sequence at IV?

Ques 28 General Aptitude

""Why do they pull down and do away with crooked streets, I wonder, which are my delight, and hurt no man living? Every day the wealthier nations are pulling down one or another in their capitals and their great towns: they do not know why they do it; neither do I. It ought to be enough, surely, to drive the great broad ways which commerce needs and which are the life-channels of a modern city, without destroying all history and all the humanity in between: the islands of the past.""
(From Hilaire Belloc's ""The Crooked Streets"")
Based only on the information provided in the above passage, which one of the following statements is true?

Ques 36 Geotechnical Engineering

A cut slope is made in a silty clay soil for a new road project, as shown in the figure. The locations of ground water table (GWT) and potential failure surface are shown in the figure. After the cut is made, the excess pore water pressure is fully dissipated, and the shear stress at the point A is 60 kN/m². The factor of safety at the point A for long-term stability is ______ (rounded off to 2 decimal places).
Note:
Shear strength properties of silty clay: c'=15 kN/m², φ'=15°, and c_H=75 kN/m²

Ques 38 Geotechnical Engineering

A clayey soil has a moisture content of 18%, a specific gravity of soil solids of 2.74, and a degree of saturation of 65%. The soil soaks up water during a rain event, and the degree of saturation increases to 85.2%. The change of the volume during the soaking is negligible. The new moisture content (in %) of the soil will be ______ (rounded off to 2 decimal places).

Ques 39 Geotechnical Engineering

A single pile with 450 mm diameter has been driven into a homogeneous clay layer, which has an undrained cohesion (c_u) of 20 kPa and unit weight of 18 kN/m³. The ground water table is found to be at the surface of the clay layer. The adhesion factor (α) of the soil is 0.95 and bearing capacity factor (N_c) is 9. The pile is supporting a column load of 144 kN with a factor of safety of 3.0 against ultimate axial pile capacity in compression.
The required embedment depth of the pile (in m) is ______ (rounded off to the nearest integer).
