Learning Objectives
Students will learn that:
- there are different types of motion
- motion can be controlled by mechanisms
- mechanisms can be used to transmit motion and force
- friction opposed motion
- the effects of friction can be utilised in designs
- the effects of friction can be reduced by using lubricants and bearings
- there are lubricants for specific environments and conditions
- there are bearings for specific purposes
- common products such as bicycles utilise many mechanisms and mechanical systems.

Mechanisms Module formats
The Mechanisms Module is supplied in either:
- Windows installer version. This is the most commonly used format for use with computers and computer networks.
- IMS Common Cartridge for use with IMS Common Cartridge compatible VLEs.
- File format for use with Apple Macs. (See information about using our software with Apple Macs)
Choosing the Mechanisms Module format
You can choose between the Windows installer version and the IMS Common Cartridge on the order form. To order software for Apple Mac computers, please send us an email stating which software package you would like to order by clicking on this link.
