Question

Give an example of a wheel and axle.

Answer 1

1. The handle of the screwdriver acts as a wheel and the rod of the screwdriver acts as an axle.
2. A screwdriver makes use of the wheel and axle assembly to penetrate through a body.
3. The rotational force applied to the handle or wheel of the screwdriver rotates the axle or rod of the screwdriver which in turn rotates the screw.
4. Ultimately the rotational force is converted into the linear axial force which makes the screw penetrate through a body.
