Every mechanical assembly faces a hidden challenge that can make or break product quality: tolerance stacking. When multiple part tolerances combine in an assembly, their cumulative effect can lead to parts that won't fit, assemblies that bind, or products that fail quality inspection. Understanding this phenomenon is crucial for any engineer working in manufacturing.

When running dynamic simulations in Finite Element Analysis (FEA), the stability and accuracy of your results often hinge on one critical factor: the timestep size. Among the various methods for determining appropriate timesteps, understanding Rayleigh's time offers powerful insights into numerical stability.

In precision manufacturing, tolerances are the invisible rules that determine whether your assembly will work flawlessly or fail catastrophically. Understanding how to specify and control these tolerances is fundamental to successful mechanical engineering.
