Two are enough, if not coplanar.
No.
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.
They are ALWAYS coplanar! This is because the definition says so! You have to read it first, in order to get the answer!
non-coplanar
¢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.
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.
Non-coplanar simply means not on the same plane (referring to points on a plane; geometry)
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
What is non-coplanar lines?
non-coplanar points
coplanar are points that lie on the same plane meanwhile non coplanar are points that don't lie on the same plane.
Non-coplanar, by a strange coincidence!
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
Coplanar means "on the same plane", so we can imagine that non coplanar means "not on the same plane".For example, if you draw a square and point on a piece of paper, the two objects are coplanar. However, if we were to add depth and the objects were a distance apart, they are said to be non coplanar.
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
