Is a sharpener a complex machine?

The old-fashioned pencil sharpeners that are hung on the wall and cranked by a handle are an example of a compound machine that is made up of two basic machines: the wheel and axle and a wedge. The wheel has several holes around its edge, and each hole is assigned to receive one end of the wedge. As you turn the wheel by hand, the holes bring it into contact with the opposite end of the wedge, which is driven into motion and, in turn, shaves off pieces of wood or plastic until only one piece remains attached to both ends.

These days, most people who want to write don't do so with a traditional sharpener. Instead, they buy a pre-assembled writing instrument called a "pen." These come in many shapes and sizes but can be divided into two main categories: flexible pens and mechanical pens. Flexible pens include ballpoint, felt-tip, and fountain pens. Mechanical pens have a fixed ink cartridge and a separate metal tip that screws into the top of the pen. There are also electric pens that contain both an ink cartridge and a mechanical tip connected to a battery-powered motor.

All these different types of pen share some common features. They all require some form of pressure to write with, whether it be from your own finger tips or from a brush touching down on paper.

Is a pencil sharpener a lever?

Simple machines are classified into six types: a lever, a wedge, an inclined plane, a screw, a pulley, and a wheel and axle. This is referred to as the "mechanical advantage" of the machine. Pencil sharpeners employ either a wedge alone or a wedge combined with a wheel and axle. This type of machine is known as a friction sharpener because the sharpening element (the wedge or wheel) creates friction when rotated against the point of the pencil.

Levers use the principle of mechanical advantage to reduce force requirements while increasing force capacity. A simple lever is simply a straight piece of wood or other material with one end fixed and the other free to move up and down. If we look at our pencil sharpener again, this is how it works: The bottom part of the device is fixed, while the top part can be moved up and down. As you can see, this allows us to increase the force applied to the sharpener by using a small motor or even your hand. Friction elements such as wheels or ramps allow the top part to rise higher than where it started from before another push of the button is required.

Lever diagrams show the relationship between the original force and the increased or reduced force produced by the lever. For example, if I apply 100 Newtons (10 kg) of force to the pencil sharpener and it takes me 10 seconds to reach the top, then the mechanical advantage of the device is 10.

Are scissors a compound machine?

Machines with Compound Functions A pair of scissors is a complicated simple machine that cuts something by forcing wedges (scissor blades) onto it with levers. Several complex machines are made up of many basic devices. The most common examples are the engine, motor, pump, and compressor. Scissors are unique in that they are both simple and compound mechanical instruments.

Simple machines use only one basic part to accomplish a task. For example, a paper clip is a simple machine because it uses a spring to close its jaws. Many other tools used in the modern world are also simple machines: a rocker-garden tool is simple because it functions using only two parts: a handle and a blade. If you connect a rock to a flat surface and give it a sharp edge, you have created a very effective knife.

Complex machines use more than one basic component to perform tasks. For example, an electric drill has a motor and a driver bit as components. It would be difficult for a single tool to do the work of a simple machine and a complex machine simultaneously. However, many tools do include multiple components. For example, a tape measure consists of a housing with scales and a sliding body inside the housing.
