To understand how this works, imagine you are trying to lift a heavy box onto a table. If you try to lift the box straight up, you will need to use a lot of force. However, if you place a wheel and axle under the box, you can lift the box with much less force.
This is because the wheel and axle changes the direction of the force you are applying. Instead of lifting the box straight up, you are now pulling the box up at an angle. This reduces the amount of force needed to lift the box.
The amount of force needed to lift the box is determined by the radius of the wheel and the length of the axle. The larger the radius of the wheel, the less force you will need to apply. The longer the axle, the greater the mechanical advantage of the wheel and axle.
Mechanical advantage is the ratio of the output force to the input force. In other words, it is the amount of force that is gained by using the wheel and axle. The mechanical advantage of a wheel and axle is determined by the ratio of the radius of the wheel to the radius of the axle.
The wheel and axle is a simple machine that can be used to make work easier. It is a versatile tool that can be used for a variety of tasks, such as lifting heavy objects, moving objects from one place to another, and changing the direction of a force.
