Axial Deformation Calculator: worked example
This example is generated from PROFENG's own default input set and the implemented relationship. It is not copied from a cited publication.
Relationship
δ = FL/(AE)
This calculator determines deformation from axial force, member length, area, young's modulus. Use it for first-pass mechanics and machine-design calculations with explicit loads, geometry and material inputs.
Inputs
- Axial force (force) = 100,000 N
- Member length (length) = 2 m
- Area (area) = 1,000 mm²
- Young's modulus (modulus) = 200 GPa
Working
(100000)*(2)/(((1000)*1e-6)*((200)*1e9))*1000 = 1 mm
Deformation: 1 mm
Assumptions and limits
- Loads and geometry are represented by the idealized relationship shown.
- Material behavior is treated according to the simple formula, typically linear-elastic where relevant.
- Units and section properties are consistent with the displayed equation.
- Load is axial and centered.
- Cross-sectional area and elastic modulus are uniform over the modeled length.
- Material response is linear elastic and deformation is small.
