An editorial in issue #109 of Y-Block magazine discusses Horsepower & Torque. I quote, "Torque is rotational force, alone. There is no work from the torque." (un quote) Then it goes on to explain how Horsepower is derived, in part from torque. I'm left scratching my head some about the statement "There is no work from the torque" It seems to me that rotational force is a measurement of work. No?. If it isn't, why is it used as a measurement of engine performance at all. Horsepower is a calculated amount which is subject to several variables, including altitude, air density etc. (And not to mention some of the biggest lies I've ever heard!) Also, the origins of it are suspect somewhat to start with. Plus there is gross power & net power etc. Also, the equipment used to measure it often vary in accuracy substantially. So.. can someone clerify for me the quoted statement about torque? Thanks
