Yes, a doorknob is considered a wheel and axle because when you turn the doorknob to open the door you are turning it so you can open the door.
The large part you grab and turn is the wheel. The rod down the center would be the axle.

Yes.
You are using a wheel and axle simple machine when you twist a doorknob. The wheel (the doorknob) rotates on the axle (the spindle), allowing you to easily open or close the door.
You could say a bike wheel is a wheel and axle. Also a doorknob is a wheel and axle.
No, a doorknob is an example of a Wheel & Axle.
A doorknob functions as a wheel and axle by using the knob (wheel) to turn the spindle (axle) that is connected to the latch mechanism. When you turn the doorknob, the rotational motion of the knob is transferred to the spindle, which then moves the latch in or out of the door frame. This simple machine allows for a mechanical advantage, making it easier to operate the latch with minimal force. Thus, the doorknob effectively converts rotational motion into linear motion to open or close the door.
A doorknob is a type of wheel and axle simple machine. It allows a person to apply force at the outer edge (wheel) to turn the central shaft (axle) which operates the latch mechanism to open or close the door.
A doorknob has a larger radius, which creates distance from the axis of rotation, allowing for more torque to be applied with less force. An axle typically does not have the same leverage, making it harder to turn with the same force.
No, a doorknob is not a pulley. A pulley is a simple machine that consists of a grooved wheel and a rope or belt that runs along the groove to lift or move objects. On the other hand, a doorknob is a type of door handle used to open or close doors.
