Does a Wheel and Axle Increase Distance?
A wheel and axle is a type of simple machine that consists of a wheel attached to an axle. When a force is applied to the wheel, the wheel rotates, causing the axle to rotate as well. This rotation allows for the movement of objects over a distance. However, the wheel and axle does not actually increase the distance traveled by the object. Instead, it reduces the amount of effort required to move the object. This is because the wheel and axle acts as a lever, which reduces the amount of input force required to move the object. The distance traveled by the object is determined by the radius of the wheel and the number of revolutions it makes.

Formulas
To calculate some of these concepts, we have some handy-dandy formulas:
- Distance: It’s the output force divided by the input force.
- Work: It’s the force multiplied by the distance.
- Power: It’s the work divided by the time.
- Torque: It’s the force multiplied by the distance from the axis of rotation.
Example
Let’s say you’re using a lever to lift a heavy box. The input force you apply to one end of the lever is 50 Newtons, and the output force exerted on the box is 200 Newtons. The distance from the input force to the axis of rotation is 2 meters, and the distance from the output force to the axis of rotation is 1 meter.
Using the formulas above, we can calculate:
- Distance = Output Force / Input Force = 200 N / 50 N = 4 meters
- Work = Force x Distance = 50 N x 4 m = 200 Joules
- Power = Work / Time = 200 Joules / 1 second (assuming it took 1 second to lift the box) = 200 Watts
So, by using a lever, you can lift a heavy box with less effort and do it more quickly!
