How do you solve for tension, is there a general formula to use
for emample such as this problem(this is not homework, its an example i saw )
you have 2 wires one at 60degrees one at 45degrees both wires have a weight of 5N. find the weight of the third wire that's going down?
how does one approach such a problem
I tired doing this , this way, but i' am wrong since the right answer is 6.1N
1. ||a||5Ncos60=||b||5Ncos45
2. ||a||5sin60+||b||5sin45=c
I substituted equation one into 2 and i got 6.9N
