If two ends of a rope in equilibrium are pulled with forces equal in magnitude and opposite direction,why the total tension in the rod is not zero?
If you pull each end of piece of rope with a force of 50 N (for example) you will create 50 N of tension in the rope. Think of the tension as the property of a stretched rope that allows it to exert a force at each end.Aruna Kiran said:Could you please elaborate your answer? I still can't get it.
Tension is a force that is created when there is a pull or stretch on an object. In a system, tension can arise due to various factors such as differences in forces acting on the system, friction, or external forces acting on the system.
The total tension in a system is not zero when there are multiple forces acting on the system in different directions. This can result in a net force, which leads to tension in the system.
In theory, tension can be eliminated by ensuring that all forces acting on a system are balanced. This means that the forces are equal in magnitude and opposite in direction, resulting in a net force of zero and therefore eliminating tension.
Tension can have both positive and negative effects on the stability of a system. In some cases, tension can help to keep a system in equilibrium by balancing out other forces. However, excessive tension can also cause a system to become unstable and potentially lead to failure.
Tension is not inherently good or bad. It is simply a force that can have different effects depending on the circumstances. In some cases, tension can be necessary for certain structures or systems to function properly. However, too much tension can also have negative consequences, so it is important to carefully consider and manage tension in any given system.
