Try these first

1. 1.

   What is the main advantage of using aluminum for utility structures?

   Hint

   Think about the properties that make materials ideal for outdoor use.

2. 2.

   Name one type of utility structure that uses aluminum.

   Hint

   Consider where you see power lines in your neighborhood.

3. 3.

   What is a benefit of using aluminum for overhead transmission lines?

   • A. High reactivity
   • B. Lightweight
   • C. Higher cost
   • D. Less strength

   Hint

   Think of the physical properties of the materials.

4. 4.

   Do mobile towers made of aluminum resist corrosion?

   • True
   • False

   Hint

   Consider the lifespan of aluminum structures in different weather.

5. 5.
