gen x posted the thread High School Why higher speeds need more power if the backward force is the same? in Mechanics.Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at... -

gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.You mean point where cruves from lower and higher gear intercept? yes here torque at wheel are the same
-
gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.Torque at wheel is smaller in 4th gear then in 3rd gear, acceleration is smaller in 4th gear compare to 3rd gear.

gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.In one gear (ex. in 3rd gear), max torque on wheel(max thrust=max acceleration) is not at engine max power, it is on engine max torque...

gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.Yes manfacturer do that based on some calculation, they do this to get max acceleration. But if they add few more gears and make them...

gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.Optimal rpm window is "power band" or "rpm power window" that engine use for max acceleration. you can see this engine operate in rpm...

gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.Yes that is instatenuos acceleration for that specific rpm, but power and torque change in my operating rpm window, so called "power...

gen x replied to the thread Undergrad Calculate acceleration from power/torque graphs.Thanks. I choose random photo from net. We can look at this, just assume both have same max power. Is there any advantge for engine...

Let say we want find out acceleration of two cars with same max power, comparing only power/torque graphs, both cars are 100% identical...
