The diameter of the pin to be used at the B point in the brake mechanism in the figure is dB = 12 mm and the diameter of the control rod connected to this point with a pin at the C point is designed as dc = 10 mm. Since the maximum force that can be applied to point A on the brake mechanism by the machine operator is F = 600 N, calculate the values of the minimum tensile yielding strength that the pin and control rod materials should have. (Dimensions are in mm)|

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.
