The concurrent forces are the one are somewhere touching the axis of rotation. If any of the force is touching that axis, that force is not considered, or is insufficient to cause a rotation. If a force is concurrent then the perpendicular distance of the force from the line of axis is zero, thus no rotation. As we know rotation is caused by moment.

Concurrent and Non-Concurrent Forces in Free Body Diagrams
Concurrent and non-concurrent forces play a crucial role in free body diagrams as they determine the overall equilibrium and behavior of the system. Let's understand the difference between the two:
Concurrent Forces:
- Concurrent forces are forces that act on a common point or intersection within a system.
- These forces can be represented by a single point in a free body diagram.
- Since they intersect at a single point, they do not cause rotation in the system.
Non-Concurrent Forces:
- Non-concurrent forces are forces that do not intersect at a single point within a system.
- These forces create a moment or torque that causes rotation in the system.
- In a free body diagram, non-concurrent forces are represented by separate vectors originating from different points.
Explanation:
In the context of the problem statement, it is mentioned that the forces in the free body diagram do not cause rotation. Therefore, the correct answer is option 'B' - Concurrent forces. These forces, acting on a common point, do not create a moment or torque that would lead to rotation. Instead, they contribute to the overall equilibrium of the system without inducing any rotational effects.
