Values for calculation

$ \{t\in\mathbb{R}\mid t>0\} $
This set includes all real numbers that are greater than zero. Therefore, it contains only positive numbers. Zero and negative numbers are not included in this set.
$ t $ $ \mathrm{mm} $
$ \{M_1\in\mathbb{R}\mid M_1>0\} $
This set includes all real numbers that are greater than zero. Therefore, it contains only positive numbers. Zero and negative numbers are not included in this set.
$ M_1 $ $ \mathrm{Nmm} $
$ M_2 $ $ \mathrm{Nmm} $
