Engineering Studies – H2 Transport Engineering – Mechanical Analysis
This topic builds on the simple machines topic from the Biomedical Engineering module. The definition and purpose of a simple machine is reviewed and the key concepts of calculating ‘mechanical advantage’, ‘velocity ratio’ and ‘efficiency’ are developed.
- The Definition of a ‘simple machine’
- Identifying simple machines within more complex mechanisms
- Calculating mechanical advantage, velocity ratio and efficiency in machines
- Define the purpose of a simple machine.
- Name the various types of simple machines and a common application for each.
- Identifying simple machines that form part of more complex mechanisms.
- Define ‘load’ and ‘effort’.
- What is a fulcrum?
- Define a mechanical advantage.
- Define velocity ratio
- Define the principle of work
- How is efficiency calculated?
- List reasons why machines are not 100% efficient.
- Define what a lever achieves.
