Lesson Plan: Lami’s Theorem Mathematics • Second Year of Secondary School
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to solve problems about the equilibrium of a particle under the action of three coplanar forces using Lami’s theorem.
Objectives
Students will be able to
- state and understand Lami’s theorem,
- use Lami’s theorem and the sine rule to find missing forces and angles in systems of three coplanar forces in equilibrium,
- solve real-world problems using Lami’s theorem.
Prerequisites
Students should already be familiar with
- the sine rule,
- forces in equilibrium.
