Homework Statement



So there's a block hanging from the wall and two strings are sustaining it, but they're at different angles.

Homework Equations


FAy= FACos(angle)
Fnet=ma

The Attempt at a Solution


Er, well, I can do this problem when the two strings are at the same angle (so they have the same tension), I just find the FAy using trig... but I don't know how to do it when the angles are different. Can anyone point me to some problems online or help? my textbook doesn't have anything.

You do it the same way, you just have two different tension variables, say T1 for string 1, and T2 for string 2.

Oh sorry, I forgot to write that one of the T is 12N and you have to solve for the unknown T.

Doesn't change anything. So now T1 = 12 N. You still solve it the same way. Resolve your forces into their components using trig, and sum them up in each direction. Use the equations you get to solve for what you are asked to find. Give it a try.
