" "tensile strength" and "ultimate strength" are used interchangeably to refer to the failure point of a material under a tensile (tension), that is what I alway understood. I wanted to cross check my understanding. Today I spoke to a guy who ran the test lab at US Steel. He agrees with "tensile...

Thanks for the info. The hour is late so I will hit this tomorrow. One problem is the vocabulary. Without much thought of the use of the word tensile, I always took that to mean ultimate. When we were addressing yield, yield was explicitly stated. Articles will speak of hardness correlating to...

I have found sources that state hardness can't be correlated to yield strength, but only to ultimate strength. Other sources state the opposite. Yet other sources claim you can do both with different equations. Can someone direct me to a source that addresses my question, or addresses the...

Lincoln welding has several good books at very reasonable prices.

When I read the brief title I did not know the end game was space travel. If you stay put on mother Earth I suggest ME and if you can take your electives or extra classes in Aero do so. I had similar thoughts years ago, leaning towards Aero. But it hit me one day, post Apollo Program, that it...

I would be happy to offer guidance in areas I am proficient in.
