Stress
Stress is simply defined as the ratio of applied force to the resistive
area.
𝜎 =

𝐴
True stress is the applied load divided by the actual cross-
sectional area (the changing area with time) of material.
Engineering stress is the applied load divided by the original
cross-sectional area of material.
