Sorry. That's rocket science. If you truly believe that torque is "one power stroke" – as your signature attests – and not the force (combustion) that causes that rotation in the first place, then I can't expect you to understand rocket science. You already have combustion engines wrong.
Force and WorkIf we hold a 10 lb. weight we are applying a 10 lb. force. If we move (displace) the weight a distance of 3 feet we have done work. We have done 30 lb-ft of work.
Work = Force x Displacement
PowerPower is how much work can be done in a period of time.
Power = Work / Time or Force x Displacement / Time
HorsepowerThe definition of 1 Horsepower is displacing 1 lb. 33,000 ft. in one minute or 33,000 lb-ft / minute.
obviously force is baked into the formula1HP = 1 lb x 33,000 ft / 1 minute
