Modulus

AI Thread Summary

To calculate the modulus of rigidity, divide the shear stress by the shear strain for the material in question. This modulus is defined as the ratio of these two values and is specific to the direction of the applied stress. For isotropic materials, there is a single modulus of rigidity value. Accurate measurements of shear stress and shear strain are essential for this calculation. Understanding these principles is crucial for material science and engineering applications.

The modulus is defined as the ratio of shear stress to shear strain in the particular direction you are referring. In an isotropic material, there will be only one value for it.

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...

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...
