Tension on strings problem

  1. Dec 7, 2014 #1
    1. The problem statement, all variables and given/known data
    See image attached

    2. Relevant equations


    3. The attempt at a solution
    bii) Tc=mc(a+g)

    Need help on Ci what I did is

    (9x9.81) -uR-6g=10a

    Have no idea what to do though really

    .... this does not follow from b(i). Please show your reasoning.
    ... did you read the hint?
    But you should complete b before starting c.

    for bii i just assumed the expressions would be the same, how would i go about getting an expression for Tc?

    The b(i) equation defines a sign convention ... you should work out the derivation they did using a free body diagram.
    Then for b(ii), you want to do the same derivation, but you have to make sure the sign convention is consistent with the first one.
