    It's a trivial relationship. Why is it fundamental?

    If I'm designing something that requires a motive force, the first thing I need to know is what that force is and the speed at which I need to apply it. That gives me the horsepower required, or kilowatts, if you want to go metric. Without that info, I cannot even start to specify the prime mover, which I'd suggest is fundamental to any machine.

    But that relationship won't provide the power required. You have to consider acceleration, gradient, various resistances, etc

    As I said, you need to know the force required. That force is obviously that to overcome all these, otherwise it wouldn't be the force required. Have I said otherwise?

    I'm sure that Tuffer only wanted a simple answer relating T.E. to horsepower, which is simple but entals a second variable (speed). Perhaps if the reasons were given, better guidance could be provided!

    Oh I am quite sure that Tuffer isn't interested in us nitpicking! :)
