Mechanics - factored self weight of an object

AI Thread Summary
To find the factored self-weight of an object, first calculate the unit weight by multiplying the mass per meter by 9.81 m/s². This gives you the uniformly distributed load (UDL). To convert the UDL into a factored self-weight, multiply it by a factor, typically around 1.4. There is some confusion regarding the distinction between UDL and self-weight, which needs clarification. Understanding these calculations is essential for accurate mechanical analysis.

Mechanics -- factored self weight of an object

How would you find the factored self weight of an object, suppose you are given the the dimensions and mass per metre of the object. Would you find the unit weight first by multiply by 9.81 and then multiplying the volume to find the UDL?

leagcy21: If you are given mass per metre, then just multiply mass per metre by 9.81 m/s^2, to obtain the UDL.

Then, to make the UDL a factored self weight, you probably would multiply the UDL by something like 1.4.

Welcome to PF;
we'd expect to be given the density function - it's not clear what "mass per meter".
Per your question: try it both ways for a handy example - do you get a different answer?

I thought UDL was different from self-weight?
 

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...
