5.1. Tension Failure

Try these first

1. 1.

   What is tension failure?

   Hint

   Think about what happens when you pull a rubber band too far.

2. 2.

   What is the difference between gross section and net section?

   Hint

   Visualize a cross-section of a cable with holes.

3. 3.

   What is the difference between gross and net sections?

   • Gross includes all material
   • net excludes holes
   • Net includes all material
   • gross excludes holes
   • They are the same

   Hint

   Think about holes or cuts in a structure.

4. 4.

   True or False: Yielding in the net section is acceptable.

   • True
   • False

   Hint

   Consider where yielding can safely occur.

5. 5.

   A steel beam with a gross area of 15 in² and a yield strength of 60 ksi is subjected to a tension load. Calculate its maximum design strength based on yielding.

   Hint

   Remember to include the resistance factor in your calculations.

6. 6.

   Consider an angle connection with a net area of 12 in² and an ultimate strength of 50 ksi under tension. What is its design strength?

   Hint

   Don’t forget to account for the area and resistance factor!
