The spring is a vital part of physics, as well as every day appliances. This has allowed this mechanism to be used throughout history, even dating back to before the Bronze Age! Springs were first recorded to be used in the standard bow and arrow, as the arrow would be pulled, resulting in more tension, before it is released and the spring element allows this to travel large distances as the energy is now transferred to the arrow.
Nowadays, there are many more uses to springs, due to the development in the product (now available in compression, tension and torsion form for example) as well as the many new inventions that have occurred over time. Five of these are very much common throughout the world, which will be discovered in this piece.
We’ll start with the most iconic spring invention, as after all, the product is just a large helical spring! If you’re not familiar with the premise of a slinky, this strangely entertains its users by performing a variety of tricks. These include travelling down flights of steps and appearing levitate. These are especially popular in the United States, the country of its origin as the Slinky was invented by Richard James in 1943 in the state of Pennsylvania.
The trampoline is another largely popular invention that has only come to mainstream use in the past 100 years or so. The first modern trampoline was created in 1936 by two gymnasts, with coiled springs are used on home trampolines in order to provide the rebounding force that bounces the user back up into the air. Although there are dangers attached to a trampoline, most are made to fit many safety precautions and still enjoy a healthy use by many people today. This is also coupled with the re-emergence of trampoline parks all over the world.
Another use for a spring is in something that most people will use every day. The mattress is used as a bed in itself or a part of the bed that is made from heavy cloth, or a framework of box springs that allow for the user to feel comfortable on the bed without having to sleep on a hard surface. The spring element to the mattress allows the user to slightly sink into the mattress in order to enjoy a better sleep.
Ever wondered why some seats allow you to sink into them to allow maximum comfort? The reason is an upholder that works similarly to a mattress, this allows the person sitting down to feel like they are sitting on a soft surface. These are now popularly used in the domestic, commercial and industrial sectors as more and more products that require seats are now moving towards this level of comfort. These are used in more modern car and coaches, as this, provided by leather seating, notices the fact that the user may be sat down for sustained periods of time.
- CD Players
Due to the surge in online music streaming and portable music files, the CD Player seems like a bit of a nostalgic invention when mentioned in this day and age, however they were still popular is little as 10 years ago. CD Players used springs in order to pop up when they were pressed inwards in order to allow the user to retrieve a CD that had been previously placed into the device. This mechanism was very useful for keeping the CD protected and away from potential dust.
