4 A rectangular steel beam is held between two rigid, unyielding walls 2.25 m apart. The modulus of elastic- ity of the steel is 210 GPa, the coefficient of thermal expansion is 11.7 × 10-6 1/°C, and the cross-sectional area of the beam is 6.5 cm². If the beam temperature is increased by 30°C, what is the change in stress in the beam?

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.
