Coplanar forces are forces that lie in the same plane. When multiple coplanar forces act on an object, they can be added together to find the resultant force. In order for an object to be in equilibrium, the sum of all the forces acting on it must be equal to zero. This means that the forces are balanced and the object is not accelerating in any direction.
To determine if coplanar forces are in equilibrium, you can use the equations of equilibrium. These equations are:
1. ΣFx = 0 (sum of all forces in the x-direction is zero)
2. ΣFy = 0 (sum of all forces in the y-direction is zero)
3. ΣFz = 0 (sum of all forces in the z-direction is zero)
By applying these equations to the forces acting on an object, you can determine if the object is in equilibrium. If the forces are not balanced, the object will accelerate in the direction of the unbalanced force.

Coplanar Forces
Coplanar forces are forces that lie in the same plane. They can be represented as vectors with their tails at a common point.
Equilibrium
Equilibrium is a state of balance where the net force and net torque acting on an object are both zero.
Coplanar Forces in Equilibrium
If three or more coplanar forces act on an object and the object is in equilibrium, then the following conditions must be met:
- Net Force = 0: The vector sum of all the forces must be zero. This means that the forces cancel each other out.
- Net Torque = 0: The vector sum of the torques about any point must be zero. This means that the forces tend to rotate the object in opposite directions with equal force.
Method of Equilibrium for Coplanar Forces
One method for solving coplanar force equilibrium problems is the method of equilibrium. This method involves:
1. Choose a Coordinate System: Establish a coordinate system with x- and y-axes.
2. Draw a Free Body Diagram: Represent all the forces acting on the object as vectors on a free body diagram.
3. Sum Forces Horizontally: Set the sum of the horizontal forces equal to zero. This gives an equation in terms of the unknown forces.
4. Sum Forces Vertically: Set the sum of the vertical forces equal to zero. This gives another equation in terms of the unknown forces.
5. Solve the Equations: Solve the two equations simultaneously to find the values of the unknown forces.
6. Check the Torque Condition: Verify that the net torque about any point is zero. This condition ensures that the object is in equilibrium.
