I-Beam Sizes: Standard Dimensions in SI Units

AI Thread Summary
Standard sizes for I beams in SI units can be found on reference sites like Engineer's Edge and EFunda. For calculating deflection with two point loads and a uniformly distributed load (udl), the deflection for each load should be calculated separately and then summed. There is no special equation required for this method. The discussion emphasizes the importance of using reliable resources for engineering specifications and clarifies the deflection calculation process. Understanding these principles is crucial for accurate structural analysis.

Where can I get a list of standard sizes for I beams? (Preferably in SI units, just to save me time)

Did you try any of the reference sites like Engineer's Edge or EFunda?
 
Thanks, I found what I was looking for.If you have two point loads equidistant from the centre, and a udl, such as;

^^^l^l^^^

how do you calculate the deflection?
Do you calculate deflection for the point loads, and the udl separately, then add the results together? (I just want to make sure there isn't a special equation I'm missing)

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
