The impedance, Z, and Power triangles.

The Impedance Triangle.

Alternating current added a new complication to Ohms law. If we are working with only resistance, there is no problem as long as we use RMS values for volts and current. The math works great including the calculation for power. However, as soon as we added inductance or capacitance things started

It is time for the rubber to meet the road on starting to figure out how to build the popsicle crane boom. As you know, I have been looking at many pictures and researching crane sites to try to understand what

When I started this web site my goal is to talk about the things I like and instruct others to do the same. The goal is for the most part to not present plans and step-by-step instructions, but more to present ways to reason through problems and come up with solutions. Technique and knowledge is
