This tire is full of fluid. It was heavy, so I took the fender off and used the crane

Visited a mining school where they had a display of different I-beam connections used in buildings. Are all of these under D1.1 code?

Just got a new job and I’m going to be taking a 3G short circuit downhill test on 3/8” carbon steel plate in a few days. I was told no one has ever passed a bend test doing downhill so I am hoping for some advice so I can hopefully pass and make a good impression. They all say it’s on the cap when it fails. What are some good settings for root, fill , and cap? Any advice would be appreciated

I recently got a piece of pipe. I believe it is copper nickel alloy. I am going to do a spark test to confirm material. Does copper nickel alloy pipe give off sparks and what color? What other test can I do to determine if it is copper nickel alloy?
