Tension force at molecular level

  1. Mar 5, 2012 #1
    hey, i wanna 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 whats goin on at the molecular level in a rope when forces are applied at both ends.

    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.
