For a 'best'
symmetrical trapezoidal section of an open channel with a given area of
section and side slopes, one of the following statements holds true :

Sand drains are used to :

The soils most susceptible to liquefaction are :

The following general statement may be made about the penetration value and softening point of bitumen

The
maximum allowable compressive stress corresponding to lateral buckling
in a discretely laterally supported symmetrical I beam does not depend
upon :

A volume of 3.0 x 10⁶ m³ of ground water was pumped out from an unconfined aquifer, uniformly from an area of 5 km². The pumping lowered the water table from initial level of 102 m to 99 m. The specific yield of the aquifier is

If, for a fluid in motion, pressure at a point is same in all directions, then the fluid is :

If the shear force at a section of beam under bending is equal to zero then the bending moment at the section is

It is proposed
to widen and strengthen an existing 2-lane NH section as a divided
highway. The existing traffic in one direction is 2500 commercial
vehicles (CV) per day. The construction will take 1 year. The design CBR
of soil subgrade is found to be 5 percent, Given: traffic growth rate
for CV = 8 percent, vehicle damage factor = 3.5 (standard axles per CV),
design life = 10 years and traffic distribution factor = 0.75. The
cumulative standard axles (msa) computed are
