Yes it is home work. The reason I put in wheel diameter is that I thought the rolling resistance of the wheel along with the number of revolutions per minute and the distance per revolution might be relevant t working out the touque needed to stay at rest, not going up or down, and then the...
Can some one please tell me the equation needed to caculate the torque needed 1. to overcome gravity trying to make you roll down hill and 2. ride up hill at 10km/h for a 100kg (bike & rider) on a bike with 66cm wheels on a 10' slope?
