Kevin,

 Great explanation.  I consider the inertia ratio to be the single most important calculation when applying servos. If a motor/drive package has enough wattage to do the job at hand, and the inertia is properly matched, the system will normally work well with reasonable attention given to the mechanical details.

Maximum power transfer is often overlooked as a benefit of inertia matching.

As an EE, it looks to me like you are matching impedances (and maximizing power transfer).  It's always interesting to see the same answers come from seemingly unrelated fields/systems.

A decade from now, firmware development may be nothing more than software integration, grabbing vendor and third-party components, and meshing their APIs together to form a final system.
Design, simulation, manufacturability, and prototyping: All of these phases are being pushed forward and progressively by underlying technologies.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Pressure vessels are part of common equipment utilized in plants to store liquids and gases under high pressure. It is certain that pressurized fluids will develop stresses in the vessel, which when exceeds failure limits, will lead to hazardous incidents and fatalities.
