source-engineering-values

Find an engineering value a design needs (a dimension, a height, a material, a section size, a thickness, a tolerance, a load) from a real source instead of guessing, and record the value together with where it came from. Use whenever a phase or a question needs a number or a material the user has not given, before you write it into a requirement, a CAD model or an analysis, and when choosing a purchasable part or stock size. Covers project documents, standards, past work, component search and selection, analysis, measurement, and stated assumptions.
