I'm modeling some things in AutoCAD and I want to make sure I don't have any interferences. I want to use 3x3x3/8 structural angle iron and I've been trying to find out what the internal radius is. Any ideas?
Awesome! Thanks again. I've just got one item that I'm confused on. That would be the units. When I look at the formula for Mt and simply look at the units, I consider moments to be in lb*in which then breaks down the W to have to be in lb*in as well for the formula to work. So if W is...
Thanks for all your help on this swearingen, I really appreciate it. I've taken you last bit of advice and built myself an Excel sheet to calculate the maximum allowed load. I've attached it. Could you take a quick look at it for me? Any mistakes or false assumptions?
Thanks again in...
Ok, so if I had a circular plate of diameter = 8" and a thickness of 0.5" then the I would be 0.083 in^4 (I=(b*h^3)/12) with b=8" and h=0.5". Then I can plug in the Roark's equation for Mmax and solve for W. Correct?
The case I'm looking at is:
Uniform load over a small eccentric circular...
Ok, so my Roark's (7th Addition) just arrived and I see my case in Table 11.2 Case 19. However, the formulas are in terms of y and M based geometric variables and the load W. I want to find out the maximum that W can be, so how do I relate the M or y back to the maximum allowable stress of the...
My concern is not for the column itself, but rather having the load punch through the top plate. Perhaps yielded wasn't the proper term, but rather plastically deformed. If the load had a footprint large enough to spread across the top plate, there wouldn't be an issue. However, the stands...
I work out at a mine site, and we have a number of home made stands which are used on our heavy machinery. Most of the stands are constructed using a pipe as the column and then they have a base plate and a top plate. I've analyzed the main column using the Euler, JBJ, and Secant methods for...
