Homework Statement


I was working on a tension problem where a bar is supported by 2 cables at different angles.
I found the x and y vector components, but then got stuck at the simultaneous equations part.


Homework Equations


These are the equations i ended up with.

-T1sin(20) + T2sin(30) = 0
T1cos(20) + T2cos(30) = 9800

Not sure what to do, please help.

Well it just seems like solving a simple linear system:

T1 = T2*sin(30)/sin(20)

Then just substitute that into the second equation and solve for T2. Then solve for T1.
