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 '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...
