"The Secret of Wheels and Axles" Tools and Machinery PPT

Part 1: What is the function of the axle?

If you take off the wheel on the faucet and twist the shaft directly, will it still be easy to unscrew the faucet? Think about the function of the axle.

We can use an axle experimental device to study the role of the axle.

Think of a certain number of hook codes hanging on the shaft as resistance to be overcome;

Hooking the code on the wheel is regarded as the amount of force we exert;

Give it a try. Hanging a few hooks on the wheel can lift the hooks on the shaft.

Experiment a few more times by changing the number of hooks on the shaft.

The Secret of the Wheel and Axle PPT, Part 2: The Effect of the Size of the Wheel on the Function of the Axle

Change the wheel in the wheel and axle device to a larger wheel and do the above experiment on this wheel axle. Record the amount of force used each time.

Comparing the force used by the first two axles to lift the same weight, what do we find from the data?

Applying force on the wheel of the axle can save effort, and the larger the wheel, the less effort;

Hard work on the shaft.

Take a look, where are axles used around us? Which part of them corresponds to a wheel? Which part is equivalent to the axis?

What convenience does the axle bring to our work?
