elastic bar axial extension calculator online

Use elastic bar axial extension online for force N, length mm, area mm2, modulus GPa. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.

How to use it

Enter force N. Set length mm, area mm2, modulus GPa. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
force NMain input. Signed finite values. 10000
length mmOption. Positive values. 1000
area mm2Option. Positive values. 100
modulus GPaOption. Positive values. 200

Calculation method

extension_mm = force_N*length_mm/(area_mm2*modulus_GPa*1000) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply elastic bar axial extension to the case below, keeping the displayed units and assumptions. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.

Elastic Bar Axial Extension — worked case

Settings: length mm: 1000; area mm2: 100; modulus GPa: 200

Input:

10000

Calculated result for these inputs:

Output:

{
  "extension_mm": 0.5
}

Choose the right tool

Choose the loading case and boundary conditions before entering values. Engineering stress differs from true stress; beam and thin-wall formulas require their stated idealizations. These calculators do not establish allowable loads or safe designs.

Limitations and common mistakes

  • Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
