It is a pretty good explanation of the relationship between torque and horsepower. Of course, there is a huge caveat here... In the example, all rotating items (axles, crankshafts, wheels, tires...etc) are inelastic (solid) objects. What if the rotating item is elastic (non-solid) such as a whirlpool, hurricane, flow down a tube airflow through a vent...etc. In that case torque varies considerably with respect to ones proximity to the axis of rotation (which may, itself be moving), the nature of the fluid (density, temperature & homogenuity), frictional forces, wall or near wall conditions, disturbances in the flow....etc. You get the idea. These are things that designers of carborator venturis, brake systems, fuel systems, exhaust systems have to deal with. Meteorologists and all fluid dynamicists also have to know this stuff. Just some trivia to help you appreciate the math and physics guys out there... ;-) Cheers!! Jim - 68 Midget in Dodge City ```
