Strength of Materials

Q1: A steel bar of 5 mm is heated from 15° C to 40° C and it is free to expand. The bar Will induce

A compressive stress

B tensile stress

C no stress

D shear stress

ANS:A - no stress

When the steel is heated up to elevated temperatures increases in Ductility and Malleability properties.

So, here steel is heated up to 15 to 40-degree centigrade then Ductility is increased so the steel is no stress.
