I agree but you are completely missing the point. The gearing influences the speed the car has when it hits the trap.kasio wrote: ↑06 Apr 2017, 08:26well amho tells it sleeps. its a power on wheels. doesnt matter what gearing you use! you need as much power as you need to move trough air with this car at that constant speed. you can use whatever gearing you need it will still need same power.Mudflap wrote: ↑05 Apr 2017, 22:48What I said still stands. The only way to calculate the power is to know how the car accelerates against a known load. Not the largest load that it can shift.amho wrote: ↑05 Apr 2017, 22:36
No I didn't used torque and wheel radius method that u mentioned. (U mean this : P=TorquexRpm ,Torque=Fxr)
-----------------------------------------------
I used the following equations:
P=FxV
Where
V as car speed
F=drag force+rolling resistance force
Drag force=0.5xRhoxCdxAxV^2
Rolling resistance=(rollig coefficoint)xMxG
If the car exits the corner in 3rd gear and hits the trap at 100 mph then on the second lap exits in 4th and only achieves 90 has it lost power ?
Gearing dictates the tractive force which dictates acceleration which dictates trap speed.
