I am struggling with the concept of tension in a rope. Below specific questions.
I am understanding tension to be an elastic force between rope molecules. If so, is it fair to say the net tension on each rope molecule is zero (if rope is in rest) but there is a net tension for the rope whose direction is opposite to applied force?
What is the direction of the tension. I am reading conflicting answers for it. If a mass attached to rope is hanging. I think tension in rope is equal and opposite of weight. is that true?
Kleppner seems to mention that tension has no direction which is confusing me.
Also, does the tension vary. Mass attached to rope and hanging. does value of tension vary throughout the rope?
