Ima add something here... When you measure a materials strengths, you have to take several things into consideration. A solid bar is quite strong, but it isn't by any stretch a properly engineered part. To an engineer, tubing is stronger than a solid bar of the same diameter...
The solid bar will obviously be stronger (to us) but the thing is that the solid bar will be say... twice as strong (I'm not exactly sure on this) yet it weighs 10 times as much (1 1/2" bar vs. 1 1/2x.120 tube) so, yes it's stronger, but it is a HUGE waste of weight.
As for unspring weight, the simple measurement would be to assume the bar is 1/2 unsprung.
