Consider the following limitations : 1. Can be performed only on purely cohesionless soils 2. Plane of failure is predetermined 3. There is virtually no control on drainage 4. Non-uniform distribution of stresses 5. Principal stresses in the sample cannot be determined The limitations inherent in direct shear test include

Given that g = acceleration due to gravity and R = hydraulic mean depth, the Darcy Weisbach friction factor is related to Manning's rugosity coefficient 'n' as

A symmetrical circular arch of span 25 m with a central rise of 5 is hinged at crown and springings. It carries a point load on the arch in the span between the left hinge and central hinge. If the inclination of the thrust at the right hinge is θ measured from horizontal, then what is the value of tan θ ?

The combined motion of rotation and translation may be assumed to be a motion of pure rotation about some centre which goes on changing from time to time. The centre in question is known as

A train is hauled by 2-8-2 locomotive with 22.5 tonnes load on each driving axle. Assuming the coefficient of rail-wheel friction to be 0.25, what would be the hauling capacity of the locomotive ?
