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.

Q1/A structural part is 1-meter-long and subjected to a 50 KN load in which this part must be deformed elastically without experiencing any permanent deformation. If you know that part is made of steel, brass, aluminum, and Titanium alloys and the yield strengths and densities of these alloys are: 860 MPa, 7.9 g/cm³; 415 MPa, 8.5g/cm³; 310 MPa, 2.7 g/cm³; and 550 MPa, 4.5 g/cm³ respectively. Based on these criteria, rank the alloys from the heaviest to the lightest in weight.
