Actually, that depends on the kind of loading (i.e. static or impact).
It is true that to solve for stress, one only needs to divide F/A.
However, in an impact situation, you force is actually mass times acceleration. Therefore,
Stress = ma/A

The part of the special seismic load combo with 1.2DL+0.5LL+Em.
When I use this equation, do I apply a 1.33 increase if I choose to stay in
ASD, or do I have to multiply Em by 1.4 (to bring to strength level) and then apply a 1.7 increase.
My boss told me that Em is in strength level...
If we put d=c/H in the v equation, we'll get v=c.
Can this be true? If not how large does the universe have to be for v > c?:biggrin:
Just trying to enlarge my understanding for the expansion of the universe.
Thank you, and if I didn't have to eat, I'll go back to school and get...
Thanks for the quick reply.
So is there a value for which the universe is expanding? ie expanding at "c" or slighly less than "c".
Thanks,

Is "c" the fastest known velocity?
Hi all,
Newbie here wants to know, after a discussion over dinner with some friends, if the speed of light is the fastest known rate in the universe.
Specifically, I want to know if the universe can expand at a rate > "c".
I think not, because if the...
