Thank you rb1957, I have the Tear out strength now. I currently do not own the AISC Steel Construction Manual so i cant reference it. I would think the bearing strength would be lower with a pin diameter that is .62" in diameter smaller then the hole. Is there an equation for this?
I am currently trying to figure out the tear out strength of an A36 steel pad-eye. The hole in the pad-eye that it will be lifted from is 2" in diameter and 2.5 inches from center to the nearest edge. The problem is that the pin that will be lifting it is 1.38" in diameter and i was unsure how...
Chicopee, yes it does have holes and a pin. Thank you to everyone who is posting, they are great suggestions. I will continue working on this tomorrow and will ask any more questions I come up with. Thank you all again.
For the original 4 and 8 inch pipe I was using a program that showed me the bending moment and loading. http://www.maximumreach.com/SpreaderCap.asp . The safety factor is against yield strength which is 30000 psi. Deformation would be 0.001 inches.
By rated I meant that I found the load that could be put on the spreader before it deformed in anyway either by bending or compression. I was just told to treat it at as a 3 inch pipe to stay on the safe side and just use the thickness of the inside pipe which is 3/16" I also use a safety...
I'm currently an engineering intern at a crane company. We use schedule 40 steel pipes for our spreader bars. I have already rated 4 and 8 inch piping for spreader bars and how much load they could lift at various lengths and with various length slings. I am now faced with rating some homemade...
