Hey,

So I need a formula that will help me calculate the torque required to run 2 wheels that support a certain weight. The things I know are follows:

Total weight of the vehicle: 650-700kgs
Wheel Diameter: 16-17 inches
Average Velocity I will require the vehicle to move at: 10m/s


Basically, I want to choose a motor that will power the two wheels and will provide forward and backward motion and a switch for on/off action. To do that, I will first need to calculate the torque I require. If I left out any details please let me know:)

We need to know (a) how quickly you would like the vehicle to accelerate and (b) the greatest angle of incline you expect it to travel up. We also need to know the gear ratio you are planning to use between the motor and the wheels.
