   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.
