What the site will and will not do

The Eng Hub is an independent reference. It explains information-container naming, CDE state language, and the preliminary calculations that sit beside a model. The formula is on the page so the arithmetic can be checked. A 100 kN force on 2,000 mm² is 50 N/mm². A 100 mm solid circle is 7,854 mm². Those worked cases are the regression check for the tools.

It is not a design practice, not an appointed party under ISO 19650, and not a software vendor. It does not accept appointments, issue drawings, or approve a container. A file name that passes the checker has passed one project pattern. It has not been accepted into a common data environment.

Calculators run in the browser. Inputs are not uploaded. There is no account and no advertising script on this build. Contact is [email protected].

What to write beside the result

A review can only check this figure if the inputs sit next to it. Write the value, the unit and the assumption the form used. A diameter in millimetres and a diameter in metres are not the same reading. A force in kilonewtons divided as if it were newtons is a thousand-fold error.

The result is the arithmetic on this page. It is not a utilisation, not a selected product, and not a clause from a standard. If the number is going into a shared container, name the page, the date and the inputs. The file-name checker does not read the calculation.
