Strength Of Materials Set 2

Two closely coiled helical springs 'A' and 'B' are equal in all respects but the number of turns of spring 'A' is half that of spring 'B' The ratio of deflections in spring 'A' to spring 'B' is

Within elastic limit, stress is

The maximum diameter of the hole that can be punched from a plate of maximum shear stress 1/4th of its maximum crushing stress of punch, is equal to (where t = Thickness of the plate)

The bending moment at a point on a beam is the algebraic ________ of all the moments on either side of the point.

Euler's formula holds good only for

A composite bar made up of steel and copper bars of equal lengths are heated through 100

The neutral axis of the cross-section a beam is that axis at which the bending stress is

Strain energy is the

A vertical column has two moments of inertia (i.e. Ixx and Iyy ). The column will tend to buckle in the direction of the

A thick cylindrical shell having ro and ri as outer and inner radii, is subjected to an internal pressure (p). The maximum tangential stress at the inner surface of the shell is
