How can I determine the hp and torque needed to maintain my highway speed?
Hi I have a question about determining the hp or kw and toque I will need to run my 7000lbs project truck.
I have read lots of articles that give me some good information but I can’t seem to put all the pieces together properly and make it work out.
I can determine the rpm I need the drive shaft and motor to turn to maintain the highway speed with the gear ratios and tire size. I have gone through the hp Formulas and the Rolling Resistance. The problem I am having is determining the hp and torque needed to a speed of say 100kph and the extra hp and torque to bring it up to speed. I just can’t seem to put it all together properly.
If anyone can help or point me in the right direction it would be greatly appreciated.
Thanks for your time.
