Mechanics of solids is the study of solid materials' nature and behavior, like their deformation and motion under the operation of temperature change, force applied, phase changes, and other external or internal agents. This eLearning module will help you to perceive the anatomy of solids and how solid mechanics broadly uses sensors to describe stresses, strains, and the relationship between them. This eLearning module also creates a better clarity of the center of gravity, the moment of inertia, and its several applications. The study of solid mechanics is elementary for nuclear, mechanical, biomedical, aerospace, and civil engineering students.
