(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The 6.9 N weight is in equilibrium under the

influence of the three forces acting on it. The

F force acts from above on the left at an angle

of α with the horizontal. The 5.1 N force acts

from above on the right at an angle of 51◦ with

the horizontal. The force 6.9 N acts straight down.

What is the magnitude of the force F?

Answer in units of N.

2. Relevant equations

ΣF=0

3. The attempt at a solution

I broke the forces up into x and y components so:

ΣFy=6.9-5.1sin51°+Fsinα and ΣFx=5.1cos51°-Fcosα

What do I do now?
