About Instrument
One product. Four parts.
Instrument is a calculator you can check: the formula sits next to the number. Library is the finished models — open one and get a number. Build is where you write a model. Review is evidence checklists, a trade study, and FMEA you control. Project is drafts, saved checks, and review snapshots — on this device until you sign in, then on your account. Method, assumptions, and limits also sit on each model.
Saving a snapshot or a draft does not require an account. Sign in and that work can follow you.
Preliminary only · project context required · independent review
Designed to support
- Engineering explanation and independent study.
- Preliminary, transparent checks inside the stated model boundary.
- Comparing compatible quantities while keeping units explicit.
- Authoring a unit-aware calculator with method and assumptions attached.
- Building intuition before using a project-specific approved process.
Not provided
- A design certification, sealed calculation, or automatic compliance decision.
- A replacement for applicable codes, local amendments, specifications, or manufacturer data.
- A substitute for measurement quality, connection behavior, fabrication detail, or qualified judgment.
- Any use beyond the geometry, loading, material, and boundary assumptions shown in a workspace.
