Tolerance Analysis

An engineer at an automobile design center needs to specify components for piston and cylinder assemblies that work well together. To do this, he needs the dimensions of the components to be within certain tolerance limits, while still choosing the most cost-efficient methods. This is called an optimal stack tolerance analysis.
