"The beam is to be hoisted using three chains if the resultant force is to be 600 N directed along the positive y-axis. Determine the magnitude of forces Fa and Fb acting on each chain and the angle phi of Fb such that the magnitude of Fb is minimum. Fa acts at 30 degrees from the y-axis as shown."

This is one of the videos from the playlist "Rc hibbeler statics 12th Edition Chapter 2" videos. This video will help you to understand force vectors and their calculations.

the best, thx.
I tried using cosines law, but when differentiating, it gives sin theta = 0, the theta = 0, then I've gone crazy lol
