Compressive Stress
Compute compressive stress σ from axial force F and area A.
Inputs
Formula
σ = F/A
Slender columns also need buckling checks.
Fundamentals
Compute compressive stress σ from axial force F and area A.
This tool computes Compressive Stress from the formula: σ = F/A
History
Design theory of gears, threads and bearings matured with machine tools and standardisation (AGMA, ISO) since the Industrial Revolution.
Engineering applications
Used for transmission design, joint strength checks and component selection.

Formula
核心计算关系：σ = F/A
输入变量：
- Force F
F— N - Area A
A— mm²
输出结果：
- Compressive stress σ
sigma— MPa
假设/适用：Gearing/thread formulas assume standard, zero-backlash mounting; include error & load factors K_A.
Worked Example
根据公式 σ = F/A，取 Force F = 10,000 N；Area A = 100 mm²。
代入计算得：Compressive stress σ = 100 MPa。
Key Points
- Gearing/thread formulas assume standard, zero-backlash mounting; include error & load factors K_A.
- Compare stress with allowable stress and keep a safety factor (≥1.5, ≥2 for critical parts).
- For high speed/load also check lubrication, heat and fatigue life, not just static strength.
