Question

A vertical column has two moments of inertia (i.e. 1xx and 1yy). The column will tend to buckle in the direction of the axis of load perpendicular to the axis of load maximum moment of inertia minimum moment of inertia A steel bar of 5 mm is heated from 15 degree C to 40 degree C and it is free to expand. The bar Will induce no stress shear stress tensile stress compressive stress A masonry dam may fail due to tension in the masonry of the dam and its base overturning of the dam crushing of masonry at the base of the dam any one of the above In order to prevent crushing of masonry at the base of the dam, the maximum stress should be the permissible stress of the soil. equal to less than equal or less than more than The bending moment at a point on a beam is the algebraic of all the moments on either side of the point. sum difference The deformation per unit length is called tensile stress compressive stress shear stress strain
