Wheel and Axle
Nadia Esmail & Kiera Floyd
Wheels on a car
Water wheel (old fashioned source of water power)
What is the advantage of this?
When the force is applied to the wheel in order to turn the axle, force is increased and the distance and speed is decreased. When the force is decreased, the distance and speed are increased.
Mechanical advantage calculation....
The mechanical advantage of this machine is calculated by finding the ratio between the radius of the wheel and that of the axle.
