Tension force at molecular level

AI Thread Summary
When a force is applied to both ends of a rope or cable, the molecules within the material experience electromagnetic attraction, which keeps them in a resting state. Pulling on the rope causes deformation, moving the molecules away from this equilibrium position. The molecules then exert a restoring force, attempting to return to their original arrangement. This interplay of forces generates tension within the rope. Understanding this molecular behavior is key to grasping how tension operates at a fundamental level.

hey, i want to understand how does the molecules of a rope or cable generate tension when force is applied at both ends. consider a block of mass m hanging from a ceiling with the help of a string. please explain what's goin on at the molecular level in a rope when forces are applied at both ends.
 
Physics news on Phys.org
The molecules in a solid are attraced to each other by electromagnetic forces. When you pull on the rope, you deform it, and actually move the molecules away from their resting state. They want to go back to their resting state, and will pull in order to do so.
 

Thread 'Is calling fictitious forces not real just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
