Frame the decision
Define the component or process question, target outcome, operating conditions, and the constraint that makes the decision consequential.
METHODOLOGY
A disciplined path from question to next verification.
MechPlane uses simple, visible models to help users decide what to investigate next. A calculation without conditions is not a conclusion.
Model what is known
Use a stated deterministic relationship, consistent units, and inputs whose source is visible. A missing variable remains missing.
Screen the simple case
Identify whether the model can answer the question under its own assumptions. If it cannot, the result explains why rather than presenting false precision.
Compare real alternatives
Show the values and constraints that change an outcome between viable options. The goal is not to invent a universal optimum.
Verify the next claim
Point to the appropriate manufacturer data, drawing review, test, standards reference, or qualified engineering review before a decision is treated as final.
THE BOUNDARY MATTERS
Preliminary support is not professional signoff.
MechPlane is intentionally conservative about the point where a simplified model becomes insufficient. Safety-critical, regulated, code-governed, lifting, pressure-vessel, and release decisions require a qualified review and applicable authoritative materials.
