B What is tension and how does it affect a rope?

AI Thread Summary
Tension is defined as the inward force that a rope exerts when under stress, acting at both ends where it is attached. It is a pulling force, not a pushing force, and is not classified as a vector. The discussion confirms that tension consists of opposite forces acting on small elements of the rope, which cancel each other out, while a single inward force acts at the ends. Participants express the need for a diagram to better illustrate these concepts. Understanding tension is crucial for analyzing forces in various physical scenarios.

I have gathered everything from post “Monkey climbing up the rope” about tension.
Tension is basically a force that the rope applies back when it is under stress. It is an inward force. Tension T's direction at end points of rope where its attached to the body and ceiling is inwards. Tension is what we pull something with not push.

This video explains nicely how force applied is transmitted from one end of rope to other under tension.
Tension is not a vector.
I want to be verified: Someone said in other post I don’t know which one “tension is pair of opposite forces acting on small rope elements all along the rope ,when under tension ,cancelling each other. At the ends there is just one force acting inwards on each end”. Am I right? A diagram would be helpful.

Yes. But if you quote someone, that 'someone' is right.

Well, you should know enough by now to at least propose a diagram. Post it :smile: !

This has been discussed many times on PF, and will likely come up again, so the video might come handy.
