Question

The forces whose line of actions lie on the same line are known as​

Answer 1

The forces, whose lines of action lie on the same plane are known as coplanar forces. Concurrent forces. The forces, which meet at one point, are known as concurrent forces.

Answer 2

The forces, whose lines of action lie on the same line are known as collinear forces.

Explanation:

• When two or more forces act on a body, they form a system of forces.
• The force in which the line of action of forces is acting along the same line for a system is known as Collinear force.
• This type of system of the force is easy in simplification.
• It is because as the forces it is vector quantity, the vector math is applied and the simplification is done.
• For example: In a tug of war contest, two teams pull at opposite ends of a rope until one drags the other over a central line.
• Here, all the forces applied by the people pulling towards them are along a line i.e. along the length of the rope.
