Notations used in the pages on the Theory of Machines.
While studying the theory of machines in these pages, a student will often come across symbols and notations representing engineering terminology. Most such symbols are easy to understand, for instance, the term "D" used in connection with a pipe or tube would normally imply "Diameter"'. However, you may come across terms that are not so obvious. Therefore, for complex terms and notations, such as the use of "C" for "Modulus of Rigidity", a student feels the need for a ready reference of terms and notations.
