Can someone elaborate on Yield and tensile strength of metals and how they are measured? For instance, I'm searching McMaster Carr for various ideas and types of metals and question the strength ratings.
When the stats indicate 35,000 yield strength, is that per inch, per foot, per yard, etc? What happens when I cut it down? I'm also comparing a flat stock aluminum at 1/4" thick x 2" wide to a 2" wide(base) x 1" high(leg) x 1/4" thick and a 1/8" thick aluminum channel. The 1/8" thick channel has the same yield strength as the flat stock. Is it due to the
1/8" difference in thickness? Would a 1/4" thick channel have a greater yield? Does that have anything to do with flexibility?My objective is to weld pieces of aluminum into this shape .......
All help appreciated.
Thank you
