Don Rotolo's post talked about the stresses being greatest on the top and bottom, which doesn't match how I read the picture it's referring to. The recent images use the words "wide" and "tall", but the pictures associated with those words seem to be swapped. Help? |

Thanks for saying something. This conversation started from another thread discussing frame rails getting hit from the side which is why I modeled the beam with the load from the side and now we're mixing that convention with the typical beam loaded from top convention. I'll correct the images so that the load is on top since that seems to be the easiest to understand for anybody wandering in to this thread. *sigh* Once again, I'm making the simple complicated. |
Re: pic: Beam Bending Example
Um, sorry about that, I accept the responsibility for confusing the directions. When I wrote I was thinking of deflection force from above, but of course the image shows (showed?) the force from the side.
Just think in 4 dimensions and it'll all make sense. Don |

Is this what your looking for.....

It looks like three smaller loads, 2 up and 1 down, with fixed end faces on a shorter beam. |
Re: pic: Beam Bending Example
i put equal weight in each place but in differing directions....like you said the two going up are equal to the one going down all forces are equal to 200 lbs.

Re: pic: Beam Bending Example
I also did a different one with the exact same force and placement as you and it still worked out. ( like the one you started off with )

So from looking at the previous images I think we can safely conclude that
New images, just for squirrel Quote:
1/8" wall 1000 lbf uniform load 2.674 lbm 20318 psi max stress - Gee, why is that so much higher than the others? :rolleyes: .243 in max deflection |
