Strength of materials extends the study of forces that was begun in Engineering
Mechanics, but there is a sharp distinction between the two subjects. Fundamentally, the field of
mechanics covers the relations between forces acting on rigid bodies; in statics, the bodies are in
equilibrium, whereas in dynamics, they are accelerated but can be put in equilibrium by applying
correctly placed inertia forces.
