A) If an accurate value for the notch sensitivity is hard to find, I should consider the fatigue stress factor higher than the stress concentration factor under static loading condition in or False concentration design. True B) If the same design safety factor is used, the reduction of the shaft diameter from 2" (inches) to 1" (inch) would cause the deflection of the shaft increases approximately ( ) times.

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.
