old said: (quoted from post at 22:47:13 11/24/14) Well I could not go to that site due to dial up but yes few understand HP and torque power and how RPMs can add HP but not add torque power and all in all not all things are as simple or add up when the work has to be done
And even fewer understand why physics defines
work = force x distance
and
power = work x time = force x distance x time.
A horse carrying a 330 pound load 100 ft does 33,000 pound-feet of work. If it takes the horse 1 minute to do that work the horse expends 1 full horse power of energy doing the work. If the horse does it in 2 minutes the horse expends 1/2 horsepower of energy doing the same work....
When you understand what that means in real life to the horse or an engine performing that work you will truly comprehend why and how physics differentiates power from work.
