7. Mechanical Testing of Steel and Aluminum

Try these first

1. 1.

   What does the tensile test measure?

   Hint

   Think about how materials stretch.

2. 2.

   Which test measures resistance to indentation?

   Hint

   What indicates a material's strength?

3. 3.

   What does the tensile test primarily determine?

   • A. Yield strength
   • B. Hardness
   • C. Impact toughness

   Hint

   Focus on what this specific test evaluates.

4. 4.

   True or False: Hardness tests are only used for steel materials.

   • True
   • False

   Hint

   Consider the versatility of testing methods.

5. 5.

   Design a test plan for a new aluminum alloy used in construction. Detail which mechanical tests you would prioritize and why.

   Hint

   Consider the application and performance needs.

6. 6.

   A material has a low hardness value but excellent tensile strength. Discuss potential applications and concerns when using this material in construction.

   Hint

   Think about trade-offs in material selection.
