Vibrations are mechanical waves, which can be transmitted through elastic solids. But not all vibrations are the same. We may distinguish two types of vibrations: longitudinal and transverse. The different types of vibrations can be classified according to their wavelength, amplitude, frequency and other parameters. This text is an introduction to a blog post about mechanical waves with an example about how certain frequencies from a train cause my model car to vibrate on its own without being pushed by the train's movement or hitting any bumps along the way. It is informative and factual because it explains what vibration is, what causes different kinds of vibrations, and provides an example experiment that displays these vibrations in action. This post is a way to teach students about vibrations, because there are limited facts about them that can be found in the classroom. In the United States, mechanical vibration occurs when a car drives across railroad tracks, when a valve in a train passes by, or when a locomotive diesels its engine. In engineering classes, an engineering professor might explain that vibrations occur because of mechanical energy in motion. For instance, in this blog post's example experiment, if the train's wheels hit the track's indentations at a higher speed than what they were designed to do, vibrations would occur in the wheels and rails. But it depends on how much energy is in motion and how strong this energy is. In this blog post, the author explains that his model car was vibrating after it drove across a very rough, cracked road due to the actual construction of the road. In this example, the wheels were in fixed position and even though there were no bumps in the road for them to go over, their friction against surface still caused vibrations in them and transferred them to other parts of the car. These vibrations moved through everything within its frame and caused it to vibrate and shake.Vibrations in Mechanical Energy http://www.slideshare.net/trafficrobot/mechanical-vibrations-mechanical-energy https://www.slideshare. net/trafficrobot/vibrations-in-mechanical-energy The model car example is a way to teach students the basic concepts about vibrations. In this discussion, there are key words and phrases that can be used to simplify understanding of mechanical vibrations. There are not many resources that have been created to understand vibration in mechanical systems, so materials on this subject need to be created so students can understand this concept and build on it once they understand and learn more about it. Mechanical vibrations occur when the car was moving across the rough road, but what caused my model car's wheels and frame to vibrate?Explaining Vibrations in Mechanical Energy http://www. slideshare.net/trafficrobot/mechanical-vibrations-mechanical-energy http://www.slideshare.net/trafficrobot/mechanical-vibrations-mechanical-energy This example shows how difficult it is to explain vibrations in mechanical energy, because after the student completes the experiment, there is no way to understand what actually happened or how it happened. This means that physics professors need to do more experimentation and research in order to be able to explain vibrations in mechanical systems better. cfa1e77820
