Fatigue life is a mechanical and scientific term that relates to how long an object or material will last before completely failing because of concentrated stresses. There are a number of different factors that can influence fatigue life including the type of material being used, its structure, its shape and temperature changes.

Any material that you use will have pros and cons for use. There will be a number of benefits that you can get from adding certain elements to your object. Shear modulus refers to how the material might respond to certain types of strain. There are a number of different types of strains to consider when choosing your materials and application. The other types of strain include bulk modulus, which is the material’s response to uniform pressure. Another consideration is how a material responds to linear strain such as what occurs when there is strain applied to opposite ends or sides of the material.

Vibration is a unique concept in that it can be both a desirable and undesirable form of energy. It can be created by a simple motion and then move on its own until it returns to its natural, resting state. It can also be generated by a mechanical force that causes the vibrations on a regular basis. To protect some materials and components, there are a number of protective measures that can include vibration isolators or vibration dampers. There are some materials that can perform both types of actions for the object.

In the world, there are many different kinds of energy. Each of these types of energy behave in different ways in different situations and can be generated or expelled in different ways as well. Kinetic energy is built up in an object by motion and can be defined as the energy that is needed to either slow it down or speed it up. Perhaps the easiest way to describe kinetic energy is by looking at the typical roller coaster. As it climbs the hill, it builds up kinetic energy.  At the top of the hill, the coaster will have its highest level of kinetic energy, which it will then use as it works toward decelerating with the goal of hitting a lower speed by the time it reaches the bottom of that hill. The amount of kinetic energy is always relative, which means there are a number of factors that can determine how much energy is able to build within the object in question.

Machines, regardless of their purpose or their size, have a number of parts. Even the most rudimentary machine will have at least a few moving parts. The more parts involved, the more important that energy and energy resonance will become. Energy dissipation, when done correctly, can extend the life of the machine and can also make it work more efficiently.

Imagine that you are a runner. You set off onto the open road, your shoes laced up, water bottle in hand and dedication in your heart. You stretched out, you know you are ready for this. But, not long into the run, your legs feel stiff and heavy, like they were suddenly made of pure lead and there is a shooting pain running up the shin. Every step becomes plodding, torturous. Your distance is half that of what you can handle on a treadmill. So, what gives? Do you just run better indoors or is there another explanation?

A spring, or any other mechanical part for that matter, is meant to do a certain action. It will continue to do that action until it is either forcibly stopped or until the action of other factors causes it to stop. On the other hand, the spring will not automatically start moving without an action that sets it into motion and usually, will not continue to move unless there is energy driving it to do so. In the case of the spring, it will not move up and down without someone or something making that initial movement.

In the world around us, there are many kinds of energy. Mechanical energy is potential energy plus kinetic energy that is present in the entire mechanical system and then disbursed among those components. All of the parts may have a set amount of energy to contribute but must have an action that sets them each in motion.

Have you ever watched your washing machine while it is on the rinse cycle? Does it move around a lot, or even “walk” across the floor? This is because the vibrations from the machine at work is causing other parts to move, and over time, this can do some significant to the machine.

Do you have a teenager in the house who is in a band, and that band practices in your home? After a while, this is not only going to drive you nuts, it may also start to get on your neighbors’ nerves, and you may start receiving complaints, especially while the band is still in the learning stages. If you have the time and the money, and you really want to help your budding musician, you may want to invest in sound proofing a room in your home, such as a basement or attic, so your teenager and his or her friends can practice to their hearts’ content without bugging anyone. To do this, you need to have a really good sound absorbing material, and the best one available on the market today is Sorbothane.
