Forces in equilibrium occur when the resultant force acting on an object is zero. This document covers the representation of two or three forces in equilibrium using the triangle of forces, illustrating how the magnitude and direction are depicted. The teacher encourages questions for further clarification.

2. FORCES IN
EQUILIBRIUM
An object is said to be in
equilibrium of forces
when the forces acting on it produce a zero
resultant force.

3. 3 TYPES OF FORCES IN
EQUILIBRIUM

4. EXAMPLE

5. 2 FORCES 3 FORCES

6. THE TRIANGLE OF FORCES
The three forces can represented 3
forces acting on the an object.
The magnitude of the forces can be
represented by the length of the sides
the triangle.
They are drawn in sequence according
to the directions of the forces.
