bii) Tc=mc(a+g)
... this does not follow from b(i). Please show your reasoning.
Have no idea what to do though really...
... 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.
