6. What are some properties commonly associated with metallic materials?
12. What is the most common static test to determine mechanical properties?
17. How is the offset yield strength determined?
18. During the plastic deformation portion of a tensile test, a cylindrical specimen first maintains its
cylindrical shape (increasing in length and decreasing in diameter) then transitions into a state called
“necking.” What is the explanation for this behavior?
24. What is the toughness of a material, and how might the tensile test provide insight?
34. What are the similarities and differences between the Brinell and Rockwell hardness tests?
58. What mechanical property changes are typically observed when temperature is increased?
Problems:
1. Select a product or component for which physical properties are more important than mechanical
properties. a. Describe the product or component and its function. b. What are the most important
properties or characteristics? c. What are the secondary properties or characteristics that would also be
desirable?
