Options and example settings

OptionChoices / valueExample default
outer diameter mmMain input. Positive values. 40
inner diameter mmOption. Zero or positive values. 30

Calculation method

I_mm4 = pi*positive(outer_diameter_mm^4-inner_diameter_mm^4)/64 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply hollow circle second moment of area 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.

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.
