A cylindrical specimen of a steel alloy having a diameter of 12.8 mm and a gauge length of 50.8 mm is pulled in tension and generates the stress-strain relationship shown in the figure below. Based on this information, a screw is to be designed with a safety factor of 2.5 and to handle an applied force of 8,230N. What would be diameter of the stem/shank of this screw (in mm) when it is designed? Enter your answer to 1 decimal place e.g. 1.2 Hint: Use the yield strength matched from the curve on this homework where you had to find the yield strength at an offset.

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.

Question

A cylindrical specimen of a steel alloy having a diameter of 12.8 mm and a gauge length of 50.8 mm is pulled in tension and generates the
