Homework Equations
The Attempt at a Solution
I would be able to solve it if I could somehow find [tex] \phi [/tex] to describe the angle of F3 relative to the positive x axis. Can anyone see how to solve that specific angle?
Then and can simply sum as follows
[tex]
F_{x} = F1cos(\theta) + F2cos(\alpha) + F3cos(\phi)[/tex]
and
[tex]
F_{y} = F1sin(\theta) + F2sin(\alpha) + F3sin(\phi)[/tex]
and
[tex]
F = \sqrt{F_{x}^{2} + F_{y}^{2}}[/tex]
Then let [tex]\beta[/tex] be the resultant angle,
[tex] \beta = tan^{-1}(\frac{F_{y}}{F_{x}} ) [/tex]
