Post lab on Tension

  1. Feb 7, 2013 #1
    Hello,

    I am stuck on this post lab question. I have tried to answer questions 1 and 2 but I am unsure of my answers, could someone verify them to make sure I did this correctly? Also, I have no idea how to do number 3! I included screen shots of the problem.

    Thanks very much.
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    1. I agree with your answer - the tension are identical, so one cannot distinquish between the two.
    2. When some of B's mass is transferred to A the tensions between the two carts will decrease, so I agree with you again - the pull is less in 2.
    3. The tension in all the strings, or all of the tensions, are the same throughout the system when held still. Form this you can calculate the mass of the hanger.
