FOR SURE Politicians are indeed that way.
Sorry I didn't find that formula for you Rich, its HP = Torque x RPM divided or multiplied by that dern fudge factor lol which is some constant number.
Torque is that turning or twisting force typically measured in Foot Pounds,,,,,,RPM you know what that is,,,,,,and HP is one multiplied by the other (plus fudge factor).
A lower RPM Two cylinder Deere with that long stroke can develop as much HP as a short stroke (therefore less torque) Oliver but its running at a faster RPM and since HP = Torque x RPM the actual on paper HP can be the same
Also consider my Unstyled B John Deere tractor is rated at something like 12 HP at around 1200 RPM while my pansy sissy lawn more is rated maybe more HP BUT THATS AT 3600 RPM. And if coupled to a plow (even if geared and weighted down), which you think would pull it best LOL
Hope this helps you understand the engineering and physics relationship among all three components, take care now
