Thermal Stress In Rigidly Fixed Rod

A steel wire is rigidly fixed along diameter of aluminium ring of radius R as shown. Linear expansion coefficient of steel is half of linear expansion coefficient for aluminium thent he thermal stress developed in steel wire is:

Thermal stress does not depend upon

Thermal Stress || Examples OF Volume Expansion, Apparent Volume Expansion

A rod of aluminium is fixed between two rigid support. If the temperature of rod is increased by 10°C , then the thermal stress on the rod is (Take Y= 7×10^10 Pa and alpha =2.4* 10^-5 K^-1 )

Elasticity: Longitudinal, Shear, Volumetric stress and strain | Elongation of rod under own weight Thermal stress | Elastic energy | Torsion
