A composite bar is subjected to a tensile load of 115 kN. Bar 1 is rectangular cross section with width of 25 mm and thickness of 9 mm. The modulus of elasticity of bar 1 is 89 GPa. The second bar is circular cross section, and the diameter of the bar is 26 m. The modulus of elasticity of bar 2 is 74 GPa. Length of the bar is 3.4 m. Calculate the stresses in each bar. Also determine the strain in bar2.

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.
