The maximum frictional force which comes into play when a body just begins to slide over another surface is called

An arch with three hinges, is a structure

The M.I. of hollow circular section about a central axis perpendicular to section as compared to its M.I. about horizontal axis is

The tensile force required to cause an elongation of 0.045 mm in a steel rod of 1000 mm length and 12 mm diameter, is (where E = 2 × 10^6 kg/cm2)

The property of a material by which it can be drawn to a smaller section, due to tension, is called

The possible loading in various members of framed structures are

A simply supported beam of span L carries a concentrated load W at its mid-span. The maximum bending moment M is

The following assumption is not true in the theory of pure torsion:

If three forces acting in different planes can be represented by a triangle, these will be in

A simply supported beam carrying a uniformly distributed load over its whole span, is propped at the centre of the span so that the beam is held to the level of the end supports. The reaction of the prop will be
