10.3. Limitations

Try these first

1. 1.

   What is one major limitation of aluminum compared to steel?

   Hint

   Think about the cost aspect in materials.

2. 2.

   What happens to aluminum at temperatures around 660°C?

   Hint

   Consider how materials behave under heat.

3. 3.

   What is a major limitation of aluminum in comparison to steel?

   • Lower corrosion resistance
   • Higher cost
   • Greater stiffness

   Hint

   Consider the cost-effectiveness of materials.

4. 4.

   Aluminum has a lower melting point than steel. True or False?

   • True
   • False

   Hint

   Think about how materials behave under extreme conditions.

5. 5.

   A design team is considering aluminum for a new pedestrian bridge. Discuss the trade-offs they need to consider in terms of material cost, structural integrity, and fire resistance.

   Hint

   Consider both short-term and long-term implications.

6. 6.

   In a high-rise building, aluminum is chosen for the window frames. What are the implications of its thermal expansion and fire resistance that the engineers should address?

   Hint

   Think about how different conditions affect structural materials.
