# Friction Concepts in Braking Systems

### Engineering Studies – P3 Braking Systems – Mechanical Analysis

This topic introduces the topic of friction and introduces the analysis of frictional forces. The key concepts are the ‘angle of repose’ and the ‘angle of static friction’.

Key Concepts

• Frictional force on the inclined plane
• The ‘angle of repose’.
• The ‘angle of static’ friction
• Definition of ‘kinetic’ friction

Discussion Questions

1. What is an inclined plane?
2. What is the ‘Normal’ force?
3. Define the ‘angle of repose’.
4. Define the ‘angle of static friction’.
