Lesson Plan: Equivalent System of Forces to a Couple Mathematics

This lesson plan includes the objectives and prerequisites of the lesson teaching students how to identify the conditions for a system of coplanar forces to be equivalent to a couple and find its moment.


Students will be able to

  • identify when a system of forces is equivalent to a couple and find its moment,
  • find missing forces that make a system equivalent to a couple.


Students should already be familiar with

  • resolving systems of forces,
  • force couples,
  • using trigonometry to find angles,
  • moments.
