Try these first

1. 1.

   What does ductility refer to in materials?

   Hint

   Think about how materials behave under stress.

2. 2.

   Name one material that exhibits high ductility.

   Hint

   Consider materials used in construction.

3. 3.

   What is ductility primarily a measure of?

   • Strength
   • Plastic deformation capacity
   • Weight

   Hint

   Think about how materials behave before failure.

4. 4.

   True or False: Brittle materials can undergo large deformations before breaking.

   • True
   • False

   Hint

   Consider the behavior of glass versus rubber.

5. 5.

   Considering a new bridge design in an earthquake-prone area, explain how you would ensure sufficient ductility.

   Hint

   Consider each factor discussed in detail.

6. 6.

   If you had a choice between a short, deep beam or a slender one, which would you choose for seismic applications? Justify your answer.

   Hint

   Think about how geometry affects performance.
