¢The forces, which meet at one point, but their lines of action do not lie on the same plane, are known as non-coplanar concurrent forces.
equilbrium in coplaner forces at rigid body.
non-coplanar is forces that not in same plain.
if the line of action of forces are in different plain is callled non-coplaner force
The magnitude of the resultant of two like parallel forces is the sum of the magnitudes of the forces and its direction will be same as the direction of the parallel forces.
Concurrent coplanar forces have their lines of action intersecting at a common point, allowing them to be resolved using the parallelogram law of forces. Non-concurrent coplanar forces have their lines of action not intersecting at a common point, requiring the use of the triangle law of forces for resolution.

Coplanar forces are a set of forces all of which act in the same plane. Non-coplanar forces are a set of forces in which at least one act in a direction incline to the plane formed by two of the forces.
equilbrium in coplaner forces at rigid body.
Coplanar or not, the two conditions for equilibrium are:The sum of all forces must be zeroThe sum of all torques must be zero.
non-coplanar is forces that not in same plain.
Coplanar just means that all forces act within a single plane, rather than in three dimensions. Examples aren't really necessary -- it's really a mathematical abstraction, because in the real world forces act in three dimensions.
ABCD is a squre. forces of magnitudes 1,2,3,P, and Q units act along AB, BC, CD, DA and AC respectively. find the value of P and Q so that the resultant of five forces is a couple
if the line of action of forces are in different plain is callled non-coplaner force
When all the forces of a force system act in one plane it is called coplanar force system. If the forces act in more than one plane then it is forces in space. In this case forces are not contained in one plane. When all the forces of a system pass through a common point they are called concurrent forces. Thus we have concurrent coplanar forces when all forces are in one plane and pass through a common point. Also when forces in space pass through a common point we have concurrent forces in space.
Coplanar parallel forces are forces that lie in the same plane and have the same line of action but different points of application. The conditions for coplanar parallel forces are that they must have the same direction, be non-collinear (not acting along the same line), and have magnitudes that are proportional to their distances from a common point. These forces create a system in which the net force is equal to the vector sum of all the individual forces.
These are forces which act in the same plane (coplanar, not coplanner!) and that their lines of action all meet at a single point.
