Simple Machines: Wheel and Axle

The video explains the wheel and axle as a type of simple machine. It describes the components, which include the wheel and the axle, and how they function together. The wheel and axle work by multiplying the effort force applied to the wheel, which is then transferred to the axle to overcome resistance. The mechanical advantage of this system is always greater than one and can be calculated by dividing the radius of the wheel by the radius of the axle.

How is mechanical advantage calculated in the context of the wheel and axle?

What is the relationship between the radius of the wheel and the radius of the axle?
