1.1. Steel

Try these first

1. 1.

   What is steel primarily made of?

   Hint

   Think about the basic composition of metals.

2. 2.

   Name one common use of structural steel.

   Hint

   Consider its application in construction.

3. 3.

   What is the typical Young’s modulus for structural steel?

   • 29,000 ksi
   • 33,000 ksi
   • 25,000 ksi

   Hint

   Recall the properties given earlier.

4. 4.

   True or False: The yield strength of reinforcing steel is typically less than that of structural steel.

   • True
   • False

   Hint

   Consider the functions of both materials.

5. 5.

   A building requires beams that withstand tension and compression. Analyze the choice between using W sections or S sections for the framing.

   Hint

   Consider the load paths and structural efficiency.

6. 6.

   Calculate the residual stress impact on a W section beam when subjected to uneven heating during welding.

   Hint

   Recall how cooling rates lead to different stress distributions.
