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 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
