One more attempt to educate some of you.
You supply adequate "force" (measurable torque) (not HP as it doesn't exist) on a wrench to turn the nut on a bolt when tightening it even to have rotated the nut one revolution in 1 hour. Want to turn the nut one revolution in 10 seconds? Simply apply more force (torque) adequate enough to do so. To turn the nut one full revolution in one second? Apply adequate force (torque) to make it happen! Not once was HP used in any of the 3 examples or in reality. Just need adequate "torque force" to accomplish the task! It's torque from the engine that turns the axle shaft the drive wheels are attached to. No hamsters in a squirrel cage and no horses either! How hard is that to understand?
It's always a huge laughing joke in automotive and engine design and engineering development deartments I've heard repeated over and over so many times in the nearly 40 years of my automotive design and engineering life with all of the Big 3. Quote: "HP moves the load and does the work" Their reply is and always has been that "HP is only for feeling good and gearheads but it's the torque that actually turns the wheels to the RPM's and wanted and moves the load to and at the velocity desired, nothing else!" Heard it over and over and so true! Required TORQUE is what accomplished the work/task that's done!
Without the required torque value, you cannot have any RPM's nor any calculated theoretical HP. Straight from the engine design and development engineers over and over but some backyard know it all's think they know better! Alive and well on the forums too!
HP is a theoretical calculated value but not a measurable value as a theoretical value was used to be the base value of the thought of pulling power of a horse. Horses vary greatly in pulling power just like humans do too. Could have use the pulling power of an ant too but would it be a big carpenter ant or a little biting red ant? Science and math are only to be based on measured known reliable values, not guessed at!
Carry on boys!
