-
A Newtonian fluid is one in which the shear stress is:
सही उत्तर: ख) Directly proportional to the rate of shear strain (velocity gradient)
Newton's law of viscosity τ = μ du/dy holds for Newtonian fluids such as water and air.

The Swedish slip circle method is used for:
सही उत्तर: घ) Analysing the stability of slopes
The Swedish (method of slices) approach assumes a circular slip surface and compares resisting and disturbing moments to find the factor of safety of a slope.

In a homogeneous earth dam, the top flow line of seepage (phreatic line) is approximately a:
सही उत्तर: क) Parabola
Kozeny and Casagrande showed the phreatic line is approximately a basic parabola, corrected at the upstream face.

In the IS standard Proctor (light compaction) test, the rammer used has a mass of:
सही उत्तर: ख) 2.6 kg with a 310 mm drop
Light compaction uses a 2.6 kg rammer falling 310 mm; heavy (modified) compaction uses 4.89 kg falling 450 mm.

The Engineering News Record formula is used to estimate the:
सही उत्तर: ग) Load-carrying capacity of a driven pile from driving data
It is a dynamic pile formula relating hammer energy and set (penetration per blow) to pile capacity.

-
The coefficient of volume compressibility mv is related to the coefficient of compressibility av and the initial void ratio e0 by:
सही उत्तर: क) mv = av/(1 + e0)
mv is the volumetric strain per unit increase in effective stress: mv = av/(1 + e0).

-
Secondary consolidation (secondary compression) of a clay is caused mainly by:
सही उत्तर: घ) Plastic readjustment (creep) of the soil skeleton after excess pore pressure has dissipated
Secondary compression continues at nearly constant effective stress due to creep of the soil structure, after primary consolidation ends.

-
According to the Mohr-Coulomb theory, the failure plane in a soil sample is inclined to the major principal plane at an angle of:
सही उत्तर: घ) 45° + φ/2
From the geometry of Mohr's circle tangent to the failure envelope, the failure plane makes 45° + φ/2 with the major principal plane.

-
The field vane shear test is most suitable for determining the:
सही उत्तर: ग) In-situ undrained shear strength of soft clays
The vane is pushed into soft saturated clay and rotated; the torque at failure gives the undrained shear strength in situ.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The over-consolidation ratio (OCR) of a clay is defined as:
सही उत्तर: क) Maximum past effective vertical stress divided by present effective vertical stress
OCR = σ'p/σ'0; OCR = 1 for normally consolidated clay and greater than 1 for over-consolidated clay.
