- What is a failure point? Give an example from the video.
- Why is it smarter to fix the failure point than to start over from scratch?
- How do engineers identify which part is the failure point?
- Can a design have more than one failure point? What happens then?

Vocabulary: failure point, analyze, diagnose, repair, strengthen, system.
Try it: Test your index-card tower from the previous episode under a load (place a small book on top). Where did it collapse first? That is your failure point. Reinforce only that spot and retest. Did the rest of the structure help or hurt?
