My current guess is that a logical derivation will probably split the beam into two parts and be recursive.
Glad you’re feeling better about it! Time to do some last minute brushing up, get organized, and get lots of rest before the big day.
I am accounting for safety factors and calculating static and dynamic loads. Defense manufacturing is all about project manufacturing and project accounting. I don’t really want to use equivalent UDL as this does not give a true depiction of the scenario. First, write your moment as a function of x. Deflection A star for rb for being “older, crankier, hand-calc’ing engineer. I am looking forward to seeing it, myself. I apologize if my question is ignorant.

Can you account for cantilever moments too? Wood creeps like green concrete. For the solution using Mathcadsee the attached file. You should have a structural analysis textbook that can help you with this.
Deflection Thank you for a swift response. Just seems like you are expecting a bit too much accuracy given the material being used. Go To Topic Listing Structural. If you’re more interested in the engineering aspects of this scenario, you might try one of the engineering SE sites instead. But if you have a uniform beam and a support that does not cut into it, then these formulas are pretty good. If I have a simple beam with two supports and a static load, does placing the load in the center push the beam closest to breaking catastrophic failure?
Zach Mierzejewski 7. Correct, most of those can actually be obtained from AISC. It’s easy to join and it’s free. A lot of the times you can do a combination of multi-span cases, as in superposition, and the result is accurate. Then use the same figure to get the deflection with load from zero to a.

I doubt you’ll need one that is far off from the AISC tables.
I think you’ll have to superimpose two load cases to get this one. Steel and concrete give better results, except for the uncertainty of the loadings. For Part 2, beam clamped at both ends, use their figure However, for any given point, superposition would give you the exact deflection at that point.
It also takes a long term “set” in part of the deflected shape. Email Required, but never shown.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. I can’t seem to find a deflection formula for partial UDL’s for a simply supported beam.

Are you looking for deflections for this load condition see attached??? Deflection JAE, that sounds like the condition he’s looking for.
The bending stress is greatest in the middle; and when the ends are clamped, the stress is fotmulas than if they are free to bend.

Posted October 22, I was actually going to suggest reviewing influence line methods, but didn’t want to give you something to try to pick up right before the exam if you hadn’t ever been introduced to that method.

Otherwise, I would recommend doing a few problems from the HIbbelers structural analysis book and taking the initial chapter procedure page in your notes.
