4130 CM Tubing
(OP)
landspeed(electrical) My first post!Hope somebody can help me?What would be the formula for comparing the yield strength of CM tube say 1.625 X .093.To a tube of 1.750 X .120 ?Both being the same length.Thanks Rich





RE: 4130 CM Tubing
What kind of load - point load or distributed load??
S (section modulus) = bd^2/6 - bd^2/6 - take the outer section and subtract the inner (hollow section)-assuming square tube. You look up round tube in any good engineering book.
Moment = S x Fy (yield allowable - psi)
M = P L /4 Point Load
M = w L^2 /4 Distributed
Watch units!!! - work in inches, in-lbs, psi, lbs/inch, etc.
