Mechanics of Materials is the primary course for  mechanical engineering and is used in the design of structures and machines.

A thorough understanding of the foundational concepts of the subject is important to for mechanical design whether it be designing a single structure which has to take loads or whether it is designing an elaborate Transmission systems which is undergoing dynamic loading conditions.  Mechanics of materials concepts are cornerstone of any type of mechanical design .
