Chapter 9. Stress Transformation
Introduction
In Chapter 1, it was shown that the most general state of stress at a
given point is represented by 6 components:
Normal stresses:
x, y, z
Shearing stresses:

Introduction
When a structure or machine component is subjected to
loading, not only is it necessary to investigate the resulting
stresses, but also the deformations in the structure.
