May 23rd, 2004 10:47 PM #21Sorry for the delay but my graphs keep on getting rejected despite my efforts in shrinking them to the point of obscurity. Here's the smallest copy I can manage so far, hopefully it will go through this time...

your graph correctly shows how the power curve behaves with changing gear ratios ... and of course it shows that lower gear allows for higher acceleration but lower top speed as your insight suggest
but the area under the curve is the product of power and rpm which is not energy (neither do i know what is) ... energy is the product of power and time ... although rpm somehow involves time, the "r" in rpm is messing things up :confused:

May 24th, 2004 04:42 AM #23I'm glad I got that right.
You're right about the area under the curve. I've attempted an analysis and here's what I've come up with:
Area under curve=HP X RPM
= (Torque X RPM/5252) RPM
=[(Torque x RPM)/(Torque X RPM/HP)] X RPM
=(1/RPM )X RPM
= RPM/RPM
= 1
I dont know what to make of that because it doesnt look like unity to me...
Oops... Allow me to edit the above equation...
Area under curve=HP X RPM
= (Torque X RPM/5252) RPM
=[(Torque x RPM)/(Torque X RPM/HP)] X RPM
=(HP/1 )X RPM
= HP x RPM, which gets us back to square 1.Last edited by ebbfolls; May 24th, 2004 at 08:31 AM.
