1. Contextual Challenge (the problem that needs solving)
The combination of force and movement defines power, and a mechanism manages power to achieve a desired set of forces and movement. A mechanism is usually a piece of a larger process, known as a mechanical system or machine. You will investigate basic mechanisms and their operations.
