tolerance. Tolerance is the quality of requiring a larger dose of a certain drug every time to reach the same effects. For example, if you need 2-5 hits to get stoned at first, if you smoke regularly and at close intervals (every day or every other day) you will start requiring more hits to get the same high.
Tolerance analysis is the general term for activities related to the study of potential accumulated variation in mechanical parts and assemblies. Its methods may be used on other types of systems subject to accumulated variation, such as mechanical and electrical systems.Engineers analyze tolerances for the purpose of evaluating geometric dimensioning and tolerancing (GD&T). Methods include 2D tolerance stacks, 3D Monte Carlo simulations, and datum conversions.Tolerance stackups or tolerance stacks are terms used to describe the problem-solving process in mechanical engineering of calculating the effects of the accumulated variation that is allowed by specified dimensions and tolerances.ts methods may be used on other types of systems subject to accumulated variation, such as mechanical and electrical systems.
