Thermal Stresses in Mechanics of Solids Quiz

The equation for the expansion of length when the support is allowed to expand freely is given by: $δT = α∆TL$, where δT is the temperature strain, α is the coefficient of thermal expansion, ∆T is the change in temperature, and L is the original length.

The equation for the stress and strains when supports are fixed is given by: $stress = α∆T*E$, where stress is the stress produced, α is the coefficient of thermal expansion, ∆T is the change in temperature, and E is the modulus of elasticity.

The equation for actual expansion when the support yields by δ is given by: $Actual expansion= Expansion due to rise in temperature - δ$
