Hello BridgeSmith,
I totally understand how inertia is calculated by unit of area (mm2). That's easy : I(x or y) = Sum (ri)2 * Ai [in mm4] or I(x or y) = Sum (ri)2 [in mm4 / mm2]
My question was just regarding the use of such a result in (mm4/mm2). My guess was that the typical calculation of...
Hello,
I am reposting my question to ensure that I understand the why the inertia is expressed in mm2.
I want to ensure that the ''mechanics'' in coherent even with an inertai expressed in mm2.
I understand now that the I(x or y) is actually expressed in mm4/mm2.
The areas from the moment...
Hello everyone,
As a mechanical engineer working as a structural engineering, I still need to gather and understand the structural engineering theory.
I have a hard time to understand the moment of inertia of a bolt group (Ix and Iy).
Let's say that you have two columns of 3 bolts each...
