Explain how the mechanical advantage of a wheel and axle change as the size of the wheel increasesThanks!
The smaller the wheel, the more horizontal force or drive force will be delivered to the road surface. If an engine/transmission/drive shaft/axle delivers 100 foot pounds of torque to a single drive wheel, and the wheel diameter is 2 feet, then 100 pounds of horizontal force or drive force is delivered at the surface of the road. If the wheel diameter is 4 feet, then only 50 pounds of horizontal force is delivered at the road.
