Answer 2

The option which is not the example of a simple machine is option a: Wheel.

• Simple machines have fewer moving components and, and need reduced human effort to operate.
• A wheel is not an example of a basic machine because it is difficult for a person to move or roll it when only a wheel is present, and it does not act as a machine in this situation.
• If it is fitted with an axle, the wheel can be readily moved at a faster speed, reducing human effort.
• A simple inclined plane machine with reduced friction is a ladder and driveway.
• A screw is a basic machine that can be used as a fastener.
• As a result, a wheel by itself does not constitute a basic machine for humans unless it is combined with an axle.
