Plane Stress
Transformation Equations
1. Stress elements and plane stress.
2. Stresses on inclined sections.
3. Transformation equations.
To obtain a complete picture of the stresses in a bar, we must
consider the stresses acting on an “inclined” section through the
bar.
Because the stresses are the same throughout the entire bar,
the stresses on the sections are uniformly distributed.
