Tension and length

  1. Feb 12, 2012 #1
    1. The problem statement, all variables and given/known data

    how does the tension of a mass on a pole change as you move the mass towards the end?

    2. Relevant equations

    T=mg

    3. The attempt at a solution

    i thought tension was just mass times acceleration (gravity) so im not sure

    Tension is how much force [thank you LawrenceC - slip] the pole is under.
    The answer depends on the geometry.

    If the pole is vertical, for eg. then consider which parts of the pole are under tension.

    Your question is vague without some sort of diagram. Tension is force. Stress is force per unit area.

    yes the pole is vertical overhang off a table
