Consider two types of a column cross-section: a hollow square and a hollow circular section. In both cases the wall thickness is 6 mm and the area occupied by the load-bearing material is 965 mm². Find which of these two column types produces a better buckling performance with relevant calculations supporting your answer. Answer The outer size of the hollow square section can be calcaulated as mm The outer diameter of the hollow circular section can be calcualted as mm The second moment of area for the hollow square section can be calculated as mmª

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.
