Week Topic Topic Outcomes 4 Statics of Rigid Bodies in Two Dimensions Moment of a force Couples Equivalent coplanar force systems It is expected that students are able to: Determine the moment of a force about a specified axis. Define and calculate the moment of a couple. Determine the resultant of non- concurrent force systems. Explain how the moment of a force about a point relates to the principle of transmissibility.

Previously , any concurrent forces are considered in analyses when bodies are treated as particles . In reality , forces act at different points of application , so the size of the body will have to be taken into consideration. Thus the assumption that forces are concurrent is NO LONGER VALID .
