Is anyone familiar with the Roark's text that can clarify some terms for me? I am trying to clarify what Roark is referring to in the above mentioned text in the section on short beams (in the 5th edition 7.10 and in the 7th edition 8.10). Throughout the text, he uses the terms "span" and "depth" and then in the next section he uses the terms "width" and "breadth" to add to my confusion. Nowhere can I find a schematic or definition that clarifies what dimensions these correspond to.
Referring to the attached figure, I have a beam whose dimension are:
x = 0.187
y = .440
z = .430
and I am trying to figure out which case/equation I should be using: Beams of Relatively Great Depth (section 7.10 5th) or Beams of Relatively Great Width (section 7.11 5th).
I think that I might want to be using equation in section 5.10 5th ed:
[tex]\sigma = \frac{W}{t}[1+0.26(\frac{e}{r})^{0.7}]\dots[/tex]
but I certainly don't want to guess.
Any input is appreciated. Thanks
