As per IS 2720 Part VIII and Part VIII, the compaction test on soil can be done in two ways i.e. light compaction and heavy compaction. The ratio of compactive energy applied per unit volume in heavy compaction and light compaction respectively is

If a beam of isosceles triangular section, with a base of 40 mm and height 20 mm, is subjected to a shear of 3 kN then the shear stress at the neutral axis will be _____ MPa.

There are two cantilever beams of rectangular cross-section with given properties;

Beam A; depth = 1m, width = 0.5 m and

Beam B; depth = 0.5m, width = 1 m, then

Beam B is ____ weak by beam A

An undisturbed soil sample having thickness 25 mm was taken from a clay stratum 4 m thick and tested in laboratory. It was found that the time required to achieve 40% of its ultimate settlement is 4 .25 minutes. What will be the time taken by the clay layer on the field to achieve 50% of its ultimate settlement? Assume the drainage condition is same in both cases.

A beam of rectangular section is subjected to traverse loads. The shear stress at a particular section at rd of the depth of beam is 120 MPa, the maximum shear stress is ____________.

Two triangular wedges are glued together as shown in the following figure. The stress acting normal to the interface, σ_n is _____ MPa.

What would be the ratio of σ of Rankine’s theory to σ of St. Venant’s theory if principal stresses at a point in an elastic material are 1.2σ (tensile), σ (tensile) and 0.3σ
(compressive). The elastic limit in tension is 200 MPa and μ is 0.2.

The following are the observed value of an angle and their weightage, find the probable error of weighted arithmetic mean.

A mild steel flat of width 120 mm and thickness 10 mm is bent into an arc of a circle of radius 10 m by applying a pure moment ‘M’. If E is 2 x 10⁵ MPa, then the magnitude of pure moment will be

In setting up plane table at a station P, the corresponding point on the plan was not accurately centered above X. If the displacement of P was 30 cm in a direction at right angle to the ray on the ground, how much on the plan would be the consequent displacement of a point from its true position if the scale of 1 cm = 6 metres is adopted.
