Hello,
Can you tell me if there is anyway of calculating the top speed in each gear of a vehicle given its horsepower and gear ratios?
Since Power = Force*Velocity
Velocity = Power/Force
Force = Drag Force + Rolling Resistance
--> Velocity = Power / (Drag Force + Rolling Resistance)
This does give me the top speed of the vehicle but it doesn't tell me what the top speed in each gear would be?
This is how I found the top speed in each gear before:
Prop Shaft speed = Engine RPM / Selected Gear Ratio
Wheel Speed = Prop shaft speed / Final Drive Ratio
Vehicle Speed = Wheel Speed * PI * Wheel DiameterThe problem with the above is that for overdrive gears it gives extremely inaccurate and high speeds.
Thanks
