And all I need to know is the horsepower available. I want to know if it equates to enough to lift the mass of the car up the hill at the speed I want." There is always a sample exercise available somewhere. https://x-engineer.org/projects/vehi...ng-simulation/ "The traction force can be regarded a a 'positive' force, trying to move the vehicle forward. All the other forces, are resistant, 'negative' forces which are opposing motion, trying to slow down the vehicle." "The traction force [N] depends on the engine torque, === engaged transmission gear ratio, final drive ratio (differential), and wheel radius: Torque is what gets the job done. If the Traction Force isn't greater than the other forces, you're not moving forward. Yep. Most people don't need to have it explained to them. Spinning your wheels seems to describe this thread "app"-tly ;-) Yes, but very slowly, in a very low gear. There is not enough grip to allow the application of much power. -- Regards, Eric Stevens |
