patterns in math are crazy. Notice, if the truss was symetricl, it would have been 75 for the force, but since it is not, both forces are a difference of 4 from 75.. 71, 79. I would have to try another problem to see if this is a legit pattern, or just a coincidence

Hello, I might be mistaken but isn't it tension when the arrows point outward on an FBD? Tension is pulling apart, compression is squeezing it, that's how I remember it.
