Theory of Structures

Beams composed of more than one material, rigidly connected together so as to behave as one piece, are known as

At yield point of a test piece, the material

The load on a spring per unit deflection, is called

For beams of uniform strength, if depth is constant,

A composite beam is composed of two equal strips one of brass and other of steel. If the temperature is raised

A material is said to be perfectly elastic if

Pick up the correct statement from the following:

The ratio of maximum and average shear stresses on a rectangular section, is

In plastic analysis, the shape factor for rectangular section, is

A rolled steel joist is simply supported at its ends and carries a uniformly distributed load which causes a maximum deflection of 10 mm and slope at the ends of 0.002 radian. The length of the joist will be,
