Average pin shear stress calculator

Engineering calculators (Beta)

Find average shear stress in a round pin.

Inputs

Choose units and enter numbers. Full-width digits and fractions such as 1/8 or 1 3/8 are accepted. Changing a unit converts the entered value.

Results

Reference calculation only. Results do not certify suitability for an actual design or its safety.

Diagram

Inputs: select a blue symbol to edit Results: red-orange values and lines

Formula and applicability

τavg = F / (n π D²/4)

Displayed values are rounded. Diagrams illustrate the calculation conditions. Initial material and fluid properties are examples; replace them with values for the actual material, temperature and conditions.

Reference
Using this information as a reference

Equations assume particular loads, supports and deformation ranges. Check inputs, units and the applicability of each equation. Diagrams explain conditions; they are not manufacturing drawings or proof of safety.

Material values are typical values or reference ranges, not certified product properties or ready-to-use design allowables. They vary with standards, product form, dimensions, temper and temperature. Check the specifications and inspection certificates for the actual product.

Displayed safety factors and checks apply only to the supplied inputs and calculation model. They do not automatically establish the safety of a complete design, including code compliance, service life, fatigue or joints. For actual design, manufacture and use, separately verify applicable regulations and standards, product specifications, and the necessary tests and engineering review.

What this calculator does

Find average shear stress in a round pin.

Inputs, outputs and applicability

The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.

Inputs

  • Shear load F (N / kN / mN)
  • Pin diameter D (mm / cm / m)
  • Number of shear planes (1 or 2 typically) (—)

Calculated results

  • Average shear stress (MPa)
  • Area per plane (mm²)
  • Total shear area (mm²)

Formula overview

τavg = F / (n π D²/4)

Average stress assuming equal load sharing between shear planes. Bending, bearing, clearance, fatigue, thread roots and concentrations are excluded. This is not a joint safety check.

The displayed formula and conditions in the working panel apply to the currently selected model. Reference calculation only; it does not certify a complete design.
