The relationship between torque with rotation?

Relationship between power and rotation is expressed in the following equation P = T x rpm P: power T: torque rpm: rotation of the equation is seen relations with the rotation power as a linear relationship (please correct if I'm wrong). but some of the graphic in the journal of research that shows the relationship between them tends to polynomial (quadratic rank so), not linear. why be like that?

The confusion may have arisen because of the different definitions of 'torque'. Read this article for a clarification between the two different meanings of 'torque' = 'moment' and 'torque' = 'couple'. http://en.wikipedia.org/wiki/Torque Since torque (in the sense generally used in US texts) and power are both measured functions of an actual power source and both are measured by the application of braking power, both will show a curve (approximating to a polynomial) when plotted against RPM. The graphs on this page make it clear: http://www.epi-eng.com/piston_engine_technology/power_and_torque.htm I hope that throws more light on the topic for you.

The second article also clarifies the difference between 'power' and 'work', which confuses many.

if life is slow that means life is bad, it is totally a wrong thinking. you are wrong. in the long run it wins the race of life. but p=T x is a good discussion.

The reason for non linear relationship between power and torque in vehicle performance graphs is that, there are other factors in practical that affect the power and torque output. Like friction, the moment of inertia of the flywheel, etc. They affect the power and torque at different magnitudes at different rpm, so that is why practically relation between torque and power is not linear.

I think love the URLs of sand in the clutch because of all sorts of human relations is like sand in your hand. lol If it is in te; musty open arms, the sand will remain in place. smile But if you clench your hands tightly "knockout to defend it, it will burst through the sand between the" fingers. Perhaps there is nothing left in the hands, but most akann fall. sad Dating the URLs like that if maintained, loosely, with respect and to set other people free. Love relationship that will remain intact, but if on the handheld too tightly, too have, then the love affair was going off and missing. cry
