1. The problem statement, all variables and given/known data Find the tension in each cord in the figure if the weight of the suspended object is w. 2. Relevant equations F=ma 3. The attempt at a solution I've been able to handle these questions when 2 variables are involved, but having 3 has me stumped at the moment. so far i have only attempted system A. in this i focused on the horizontal aspects first, getting equations for Ta in terms of Tb and vice versa, by using the 0 horizontal components of both w and Tc. when subbing these into the vertical formula (TaSin30+TbSin45+TcSin90-w=0) i could only manage to get a new formula of Tc in terms of w and wither Ta or Tb, eg. Tc=w-1.366Ta and here i seemingly hit a dead end. please help, i'm extremely confused.
