Determine the reading of F on the spring balance by using a scale diagram



2. Relevant equations



None



3. The attempt at a solution

Am I doing it correctly?

It doesn't really make sense to me. I can't determine the force F. I only have 30degree angle and the weight.

I don't know how to draw the length of Force F. What is it should I be looking for?



Thank you!
