the cross bars actually do two jobs. first. keep it from deflecting length wise.
and the they keep the angle iron from twisting. the cross sections will be laying on every part of the iron.
and my tests from before told me the angle iron did'nt really twist by it self
... when adding constant pressure. because i got to go to my dads work over the weekend. ad i did some more tests. the iron does twist when adding fluctuating amounts of pressure.
consider angle iron like ceramic. hard to break with constant pressure. and easy to break with a hit.

i hate alot of people my age. in my physics class, we sent the last three on difference of a distance time graph and a displacement time graph.
jeez. i think they should all take biology instead. god
