A hard metal ball of 10mm diameter is slid across a soft metal surface and produces a groove of 3mm width. The interfacial shear strength is one-tenth of the bulk shear strength of the softer metal. For an experimentally measured coefficient of friction of 0.45 for the contact, calculate the percentage contribution of adhesive and ploughing components to the total coefficient of friction.

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.
