How to calculate tension in a rope?

  1. Sep 24, 2013 #1
    1. The problem statement, all variables and given/known data
    The link to the problem is here, sorry I couldn't put the diagram in so thought it was better to link!
    I need help with both questions, the attempt is for the first question.

    Many thanks for any help!

    2. Relevant equations
    Moments clockwise=Moments anticlockwise
    F=ma


    3. The attempt at a solution
    Moments clockwise=Moments anticlockwise
    5*15=TD
    75=TD
    ...?
    Not sure first bit is right tho!

    In all of these problems, do the standard analysis:

    1. Draw a free-body diagram and indicate all known forces and moments applied.
    2. Write equations of equilibrium.
    3. Solve the equations of equilibrium for the unknown forces and reactions.
