Stress
Stress is a core engineering term. Definition, usage notes, and a practical example.
Definition
Stress is internal force divided by cross-sectional area.
Why it matters
It is used to judge whether a part can operate safely.
How it is used
In a design check, first define the relevant load, dimension, material, or flow condition. Then interpret this term by its role in the formula and compare it with limits.
Stress = Force / Area
Example
A 1000 N load over 100 mm2 produces 10 MPa stress.
