9.1. Mechanical Tests

Try these first

1. 1.

   What does the tensile strength test measure?

   Hint

   Think about pulling forces applied to a material.

2. 2.

   What is the purpose of the flexural test?

   Hint

   Consider how materials behave when subjected to bending forces.

3. 3.

   What does the tensile strength test measure?

   • Bending resistance
   • Breaking strength under tension
   • Indentation resistance

   Hint

   Think about pulling forces applied to the material.

4. 4.

   True or False: The impact test measures how much a material can bend before it breaks.

   • True
   • False

   Hint

   Consider what happens when a material is hit suddenly.

5. 5.

   Design a testing protocol for a new plastic product meant for outdoor furniture, addressing each mechanical property mentioned. Consider environmental factors affecting your tests.

   Hint

   Include how each property affects the usability of the product in outdoor conditions.

6. 6.

   Discuss potential failures if importing plastics without thorough mechanical testing for a construction application. How might your testing impact design safety?

   Hint

   Think about real incidents where inadequate testing led to safety hazards.
