Question

door knob is used in wheel and axel or not​

Answer 1

Answer:

yes it is used in wheel and Axel

Answer 2

A simple door knob is another great example of the wheel and axle. The locking mechanism of the door knob is inside of the door and can only be controlled by the knob. Since it will be difficult turning the axle to open the door, we can turn the wheel instead and that does that job for us.
