Wheel+Axle Combination: Uses & Examples in Daily Life

In summary, the combination of a wheel and axle is necessary because the wheel rotates around the axle and the two can be affixed to a vehicle, allowing for controlled movement. This is why we cannot just use a wheel alone. An example of daily life where we apply force on the axle to turn a wheel is in a car differential, where the axle is used to turn the wheels and control the speed and direction of the vehicle. Other examples include a walking globe or a walking spool, where a person can apply a torque to the axle to turn the wheel and control its movement.

Hello, Respected teachers.

Why wheel+axle combination is used? Why can we not only use the wheel?
I'm confused about this, please explain it to me the reason.

And one more question; please give me an example of daily life in which we apply force on axle to turn the wheel.

Many many thanks.

You need to supply some context.

Do you know what this is?

How are you going to use just a wheel by itself if you don't have at least a short axle:

1. about which the wheel rotates
2. which can be affixed to the vehicle which rolls on the wheel(s)?

Otherwise, you go everywhere like this:

Thanks for this pic, Berkeman. Could you please explain it a bit? it will be a great help.

Just google Car Differential. If you have specific questions about what you read, post them in this thread with links to the reading, and we can help out with your specific questions... :smile:

The closest analogy to using a wheel only is a "walking globe", where a person stands on a globe (ball) and positions their center of mass a bit off center to cause the ball to move, and they reposition their center of mass by walking in the opposite direction to control the speed and/or stop the ball.

A simple example of applying a torque to an axle to turn a wheel is a walking spool, similar to ones used to hold telephone wires. The principle is the same as the walking globe, but it's easier to control.

FAQ: Wheel+Axle Combination: Uses & Examples in Daily Life

What is a wheel and axle combination?

A wheel and axle combination is a simple machine consisting of a circular object (wheel) that rotates around a central axis (axle). The wheel and axle work together to reduce the force needed to move an object.

What are some examples of wheel and axle combinations in daily life?

Some examples of wheel and axle combinations in daily life include car wheels, bicycle wheels, door knobs, and screwdrivers. Other examples include a water wheel, a rolling pin, and a steering wheel.

How does a wheel and axle combination make work easier?

A wheel and axle combination makes work easier by reducing the amount of force needed to move an object. This is possible because the wheel and axle work together to distribute the force over a larger distance, making it easier to turn the wheel and move the object.

What are the benefits of using a wheel and axle combination?

The benefits of using a wheel and axle combination include making work easier, reducing the amount of force needed to move an object, and increasing efficiency. This type of simple machine also allows for the transfer of motion from one direction to another, making it an important component in many machines and vehicles.

How does a wheel and axle combination differ from other simple machines?

A wheel and axle combination differs from other simple machines, such as levers and pulleys, because it involves circular motion. It also differs from other circular machines, like gears, because it does not involve multiple interacting parts. Instead, the wheel and axle combination uses a single wheel and axle to reduce the amount of force needed to move an object.
