Q1. In coplanar forces line of action
lie on....​

Answer 1

Answer:

There are many ways in which forces can be manipulated. It is often easier to work with a large, complicated system of forces by reducing it to an ever decreasing number of smaller problems. This is called the "resolution" of forces or force systems. This is one way to simplify what may otherwise seem to be an impossible system of forces acting on a body. Certain systems of forces are easier to resolve than others. Coplanar force systems have all the forces acting in in one plane. They may be concurrent, parallel, non-concurrent or non-parallel. All of these systems can be resolved by using graphic statics or algebra.

concurrent force system with all arrows meeting at one point

Answer 2

Answer:

Coplanar forces: The forces, whose lines of action lie on the same plane, are known as coplanar forces. Collinear forces: The forces, whose lines of action lie on the same line, are known as collinear forces.
