Res. req. can usually not be mixed with an actual physics question

| Oct 9, 2019 at 3:28 | comment | added | Chet Miller | Using Einstein summation convention, $\tau_i=\sigma_{ij}n_j$where $\tau$ is the stress vector on the surface, $\sigma$ is the stress tensor (a 2nd order tensor), and $n$ is the unit normal to the surface. This allows you to determine the components of the stress vector on a surface of arbitrary orientation from knowledge of the stress tensor (6 components) and the normal to the surface (3 components).

| Oct 7, 2019 at 17:03 | comment | added | Ponyboy Curtis | I'm looking for the derivation starting from force balance, specially the stress tensor and all assumptions of the fluid stress tensor. Thank you. | |
| Oct 7, 2019 at 15:21 | comment | added | tpg2114 | What is the starting point of the derivation you are looking for? It can start from molecular collisions or it can start from a force balance on a fluid parcel that represents a continuum. | |
