1. Find the tension in each cord if the weight of the suspended object is w. (I am only asking about part a)
2. Net force on an object in equilibrium = 0
3. part a) I know this isn't the typical solution for this type of problem but I don't understand why it's not working.
I used the sine law: (Ta)/(sin45) = (Tb)/(sin30)
Then cosine law: w2 = (Ta)2 + (Tb)2 - 2(Ta)(Tb)cos75
I combined the equations to solve for Tb in terms of w. The answer I get doesn't match the given answer, so I'm wondering if there is something wrong with how I set up the problem.
