Aqueous, You have no idea what you are talking about. This conversation will go nowhere by you typing paragraphs at a time. Torque and HP are VERY complex subjects, and the conversation must be slow and accurate, not paragraphs at a time. Do you want to debate torque with me?
No, you have no idea what I am talking about. You have no idea what first moment of a force is.
You have no idea how draw a free body diagram of an engine, and model the system elements.
You have no idea how to write the state equations for the system and solve it using linear algebra.
You have no idea what I just said.
There is nothing at all complicated about this conceptually. The hard part you are apparently referring to is calibrating your measurements, which all or most of the science folks here understand. A physicist doesn't complain to a chemist that he doesn't know how to use a spectrometer. They both understand calibration.
The reason I'm giving paragraphs at a time is that there is no conversation. There is just you not wanting to learn, and me offering suggestions of how you can get ahead.
There is nothing to debate about torque (or engine torque) because it's not controversial.
