THE SOURCE

Edits below update the same model.

# Bearing static-load screening
# Scope: Static bearing safety ratio using supplied equivalent static load.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

staticRating = 5000 N
equivalentLoad = 2000 N

factor := staticRating/equivalentLoad

check static factor target: factor >= 2

Illustrative first-order example. Checks are editable requirements, not design standards. The broader topic may require additional equations, data, and validation.

Formula and units

This example uses the following equations. Input names and units match the editable source above.

factor: factor = staticRating/equivalentLoad

Original worked example

These are the baseline values in the downloadable source. Edits above let you test your own values.

Given

static rating: 5000 N
equivalent load: 2000 N

Calculated

factor: 2.5

Assumptions and limits

Static bearing safety ratio using supplied equivalent static load.

The requirement checks use the limits written in this example. Passing a check does not establish that the model covers every load, material behavior, or operating condition in a real design.

Take it further with your agent

Napkin keeps the inputs, equations, checks and assumptions together in one study. Your agent sets it up; you change the numbers.

Try with Claude ↗

codex 'Use Napkin (https://napkin.engineering/mcp, or the local Napkin plugin) to build a study: Bearing static-load screening. Inputs: peak loads; static capacity; catalog coefficients. Outputs: equivalent static load; load ratio. Model scope: Catalog-dependent load and statistical rating-life models. Read napkin_capabilities and the current snapshot. Ask me for the values that matter, label assumptions with units, author .napkin source, validate it and apply it with napkin_source using the current revision, then open the study. Add checks for the limits I supply. Keep unsupported analyses explicit.'
