Stress
Engineering Fundamentals · Mechanical Engineering · Aerospace Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The internal force per unit area that develops within a material when external loads are applied to it.
Example in context
“The stress in the steel column stayed well below the yield point during the full-scale test.”
“Tam ölçekli deney sırasında çelik kolondaki gerilme akma noktasının oldukça altında kaldı.”
Where engineers use it
Stress analysis is central to checking whether parts survive their loads; engineers compare calculated tensile, compressive, and shear stresses against material limits to prevent yielding, fracture, and unsafe designs.
In Mechanical Engineering
The internal force per unit area within a material that arises from externally applied loads. It is measured in pascals and is fundamental in determining material strength.
“The maximum tensile stress in the beam under the given load must be kept below the material's yield strength to avoid permanent deformation.”
In Aerospace Engineering
Stress is the internal force per unit area within a material that resists deformation caused by external loads, temperature changes, or other actions. It is a fundamental measure in structural analysis and design.
“The finite element analysis calculates the stress distribution in the wing spar under maximum aerodynamic loading.”
Practice: can you use “Stress” at work?
A tie rod of known cross-sectional area carries a given axial load. Calculate the stress in the rod and decide whether it is acceptable for the chosen steel grade.
Show a model answer
“We check the maximum stress against the allowable value for the material.”
