2.1. Strength

Try these first

1. 1.

   What is the ultimate tensile strength of pure aluminum?

   Hint

   Recall the general strength range for pure metals.

2. 2.

   What happens to the strength of aluminum when alloyed?

   Hint

   Consider how alloying elements enhance mechanical properties.

3. 3.

   What is the ultimate tensile strength (UTS) of pure aluminum?

   • 50 MPa
   • 90 MPa
   • 150 MPa

   Hint

   Consider standard values for base metals.

4. 4.

   True or False: Alloying aluminum always decreases its strength.

   • True
   • False

   Hint

   Think about the role of alloying elements.

5. 5.

   Analyze a structural application where aluminum would be preferred over steel despite its lower strength properties. Justify your answer.

   Hint

   Think about environments where weight and corrosion are major factors.

6. 6.

   Calculate the minimum yield strength required for an aluminum beam supporting a load, given that the beam must not deform beyond 1% under a specific load. Assume dimensions and provide mock data.

   Hint

   Apply known formulas for strength and stress to find out the required properties.
