## Discussion Questions

##### Mechanics

- Why is mechanical analysis relevant and explain why mechanics is critical in the design of engineered products?
- What are examples of mechanical analysis?
- What might happen if calculations are incorrect in engineering?
- Describe the difference between a static and a dynamic system?
- What is the factor of safety (FOS)?
- What is a ‘convention’?

##### Calculations

- Explain the concept of gravity and mass and why an objects on the moon appear lighter than when it was on earth?
- Describe the basic concept that loads create forces that tend to distort objects and structures
- Define a Scalar and a Vector quantity
- Explain the relevance of accuracy and tolerance concepts
- List commonly used unit prefixes
- Where might simple trigonometry apply in mechanics?
- What are balanced forces?
- How is area, volume and area calculated?
