Suppose you have a friend who thinks simple machines are not useful today because of all of the complex, modern-day machines we have access to. Write a letter persuading your friend that simple machines are important in everyday life. To help make the letter convincing, give examples of commonly used simple machines. Be sure to tell how these machines make work easier. You can also mention what the result would be if we didn’t have simple machines. You must provide examples of all six machines.
Your letter must be at least 250 words or more and should include multiple paragraphs.
You must design your letter using a word processor like Microsoft Word or Google Docs.
You must include a salutation and a signature.
Dear [Friend],
I hope this letter finds you well. I wanted to take some time to address the conversation we had recently about simple machines and why they are still relevant in today's world. While it may be true that we have access to many complex, modern-day machines, simple machines still play a crucial role in making our everyday tasks easier and more efficient.
One commonly used simple machine that you may not even realize is at work is the lever. Levers can be found in many everyday items, such as scissors, see-saws, and even door handles. Levers work by reducing the amount of force needed to lift or move an object. For example, using a see-saw to lift a heavy object would require much less effort compared to lifting it directly.
Another important simple machine is the pulley. Pulleys are often used in construction, transportation, and even in our own homes. For instance, a clothesline with a pulley system makes it easier to hang and retrieve clothes without having to constantly reach up or bend down. Pulleys help to lift or move heavy objects by distributing the weight evenly, making the task much more manageable.
Wheels and axles are another essential simple machine that we rely on daily. From bicycles to cars to carts, wheels and axles make it possible for us to transport goods and ourselves with minimal effort. By reducing friction and allowing for smooth rotation, wheels and axles are indispensable in modern transportation.
Inclined planes, such as ramps and stairs, are also simple machines that we use regularly. Inclined planes make it easier to move heavy objects up or down by spreading the work over a longer distance. Think about how difficult it would be to move furniture without the help of a ramp or stairway.
Lastly, screws and wedges are two more examples of simple machines that we benefit from in our daily lives. Screws are used in construction and manufacturing to hold objects together securely, while wedges help to split objects apart or hold them in place.
In conclusion, simple machines are still important in today's world because they help us perform tasks more efficiently and with less effort. Without these basic machines, our daily lives would be much more challenging and tiring. I hope this letter has shed some light on the significance of simple machines, and I encourage you to appreciate their role in making our lives easier.
Sincerely,
[Your Name]
