Tension same at both ends of the string?

  1. Dec 4, 2011 #1
    Hey, I have a question on if the tension on either end of a string is equal. For example, if there are 3 blocks of different mass, one hanging of the side of the table and two on the top of the table, will the tension on the string from m1 to m2 be the same as the tension from m2 to m1?

    Not quite sure what you mean. If the string is massless, and the string connects two blocks without anything intervening, then yes, the tension is the same throughout.

    What's the exact scenario? Describe it more clearly.

    ok, sorry, there are 3 masses, m1, m2 ,m3, all different.
    m1 and m2 are on a table top, and m3 is hanging freely of the side of the table. they are all connected and are accelerating.

    my question is: is the tension at m1 due to m2 and m3 the same as the tension at m2 due to m1?

    Is this an accurate description?:

    m1 and m2, on the table top, are connected by a massless string; m2 is connected to hanging mass m3 by a massless string.

    If so, then sure, the tension force due to the string connecting m1 and m2 is the same on both masses.
