What Is the Core of a Section in Eccentric Loading?

AI Thread Summary
The core of a section in eccentric loading refers to the area where applied loads result in only tensile or compressive stress, crucial for understanding unsymmetrical bending. This concept is often linked to the neutral axis in asymmetric loading scenarios. The term "kernel" or "kern" describes the specific region where a compressive point load can be applied without inducing tensile stress. While resources like Hibbeler's and Beer's books on mechanics of materials may not cover this topic extensively, further research on the "Core or Kernel of a section" may yield additional insights. Understanding this advanced topic is essential for analyzing complex loading conditions in structural engineering.

Anyone know of any book on mechanics of materials that covers finding the core of a section in eccentric loading. I am not sure what the term is in english but the direct translation is core of the cross section, it is the region in which if a load is applied, there will be only tensile or only compressive stress. I have looked at Hibbeler's book and Beer's (Mechanics of Materials) and haven't found anything like it. I have encountered this question in unsymmetrical bending due to eccentric loading in an unsymmetrical cross section. Maybe it is on another subject and not mechanics of materials?

It is an advanced topic in the mechanics of materials.

The core of a section is a neutral axis, in the case when the section is subjected to asymmetric loading.

The kernel or kern of a section is the region in which a compressive point load may be applied without producing any tensile stress on the cross-section.

Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
Thread 'Where is my curb stop?'
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...
