simply supported uniform load deflection calculator online

Use simply supported uniform load deflection online for load N per mm, span mm, modulus GPa, inertia mm4. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.

How to use it

Enter load N per mm. Set span mm, modulus GPa, inertia mm4. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
load N per mmMain input. Positive values. 1
span mmOption. Positive values. 1000
modulus GPaOption. Positive values. 200
inertia mm4Option. Positive values. 100000

Calculation method

maximum_deflection_mm = 5*load_N_per_mm*span_mm^4/(384*modulus_GPa*1000*inertia_mm4) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply simply supported uniform load deflection 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.

Simply Supported Uniform Load Deflection — worked case

Settings: span mm: 1000; modulus GPa: 200; inertia mm4: 100000

Input:

Calculated result for these inputs:

Output:

{
  "maximum_deflection_mm": 0.6510416666666666
}

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.
