Writing an academic paper, one might use different labels for different entities. For example in MS Word, Figure, Table, and Equation might be used for figures, tables, and math equations, respectively. Equation labels are typically placed to the right side of the equation. What label should I use for a group of equations? Can I use equations (for example equations (15))?
Here is an example group of equations from a mechanics-related text, where different parameters of a criterion are calculated in a series of equations. what do we call such a group as a label (e.g. [label] 7)?
In this study, Mohr-Coulomb criterion has been selected in this study as the fracture criterion. Parameters of this criterion are calculated corresponding to [label]s(?) 7 to 9.
