At the risk of triggering TeeDee and Griz into a flurry of formulas, I have what I hope is a simple question about compression force on spreader bars. I have no hope of working out the math myself because I've spent way too much of my post-college life as a right brain creative geek and to be honest I spent most of my actual college life either recovering from or planning for a party.
Can I use Smee's chart from Hammock Physics 101 to figure out the compression force on a spreader bar? It looks to me as though I can use his formula for shear force (S) to easily figure out compression force on the bar.

Using Smee's formula, the total compression force on a spreader bar would be 2*S, correct? Or is it just S?
Be gentle.
