The vertical deflection of a point on a beam is equal to the moment of the area under the bending moment diagram about that point, divided by the flexural rigidity (EI) of the beam.
The 7th edition follows Hibbeler’s famous "Problem-Solving Methodology": (1) Theory, (2) Analysis, (3) Application. Here is what each chapter covers:
Stress (Chapter 1), Strain (Chapter 2), and Mechanical Properties of Materials (Chapter 3).
