A pencil sharpener is a compound machine made up of simple machines, like the screw and lever.
A pencil sharpener is an example of a simple machine known as a wedge. The blade inside the sharpener is shaped like a wedge, which helps to cut and shape the pencil tip when it is inserted and rotated.
No, it's a compound machine.
The blade of a pencil sharpener is a wedge.
A typical electric pencil sharpener uses around 20-30 watts of power. This amount may vary depending on the size and type of the pencil sharpener.
A pencil sharpener uses mechanical energy, as it harnesses energy through physical motion to sharpen a pencil.

A pencil sharpener is a type of inclined plane simple machine. The blade inside the sharpener is positioned at an angle to the pencil, allowing for the application of force over a longer distance to produce a sharp point. As the pencil is inserted and turned, the inclined plane of the blade shaves away the wood and graphite, creating the pointed tip.

Pencil sharpeners typically use a combination of a blade and a gear mechanism to sharpen the pencil. As the pencil is inserted into the sharpener, the blade shaves off the wood and graphite, while the gear mechanism rotates the pencil to achieve an even sharpening. The force for turning the gear mechanism can come from either manual hand-cranks or electric motors depending on the type of sharpener.
The weight of a pencil sharpener can vary depending on its type and material. A typical manual pencil sharpener usually weighs around 50 to 100 grams (1.8 to 3.5 ounces), while electric sharpeners can weigh anywhere from 200 grams (7 ounces) to over a kilogram (2.2 pounds). Compact and plastic models tend to be lighter, while metal or more robust designs may be heavier.
