🔒 Part 1: Safety Harness Systems Research

1. Research and describe how each safety harness system works:

Lap Belt:

Three-Point Harness:

Five-Point Harness:

2. Compare the harness systems by rating each from 1-5 (1 = poor, 5 = excellent):

Harness Type	Safety Rating	Comfort Rating	Practicality Rating
Lap Belt	____	____	____
Three-Point Harness	____	____	____
Five-Point Harness	____	____	____

3. Which harness system offers the best balance between safety and practicality for everyday vehicle use? Justify your answer:

💥 Part 2: Crumple Zones Analysis

4. Define what a crumple zone is and explain its primary function in vehicle safety:

5. During the crash test video analysis, observe and record the differences between rigid and cushioned impact zones:

Rigid Impact Zone Observations:

Cushioned/Crumple Zone Observations:

6. Explain how energy is transferred and absorbed differently in rigid versus crumple zone impacts:

7. What are the potential disadvantages or trade-offs of having crumple zones in vehicles?

🎯 Part 3: Critical Evaluation

8. Based on your research, which combination of safety features (harness type + crumple zones) would you recommend for different vehicle types? Complete the table:

Vehicle Type	Recommended Harness	Crumple Zone Priority	Justification
Family Car	_____________	_____________	_____________
Racing Car	_____________	_____________	_____________
School Bus	_____________	_____________	_____________

9. What ethical responsibilities do automotive manufacturers have when designing safety systems? Consider the balance between cost, effectiveness, and public safety:
