Fluid mechanics

Automotive service technicians and mechanics might work at gasoline stations or at automotive parts, accessories and tire stores. But an overwhelming majority of them work for automobile dealers or in the automotive repair and maintenance industry. These technicians are especially important in our car-driven society. That's why people place so much importance on finding a high-quality mechanic. From fairly routine tasks such as changing a car's oil or swapping out its air filter to more complex…

Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

Introduction It has been a puzzling question in fluid mechanics for quite some time as to why golf balls are designed with dimples. In the 1800’s it was discovered that a ball with scuffs in it flew through the air more consistently than a smooth golf ball.6 Manufacturers started incorporating patterns to golf balls to try and find which gave a more stable and reliable flight pattern. In the 1900’s it was determined that the strategic placement of indentations maximizes lift while minimizing…

A fluid in which the viscous stresses taken place from its flow at all the point are linearly proportional to the rate of change in its deformation over time is called Newtonian fluid. Newtonian fluid explains the relationship between the shear rate and the shear stress is linear with the proportionality constant, which is to be referred as the coefficient of viscosity. Non-Newtonian fluid is a fluid where the properties of fluid flow are not similar with Newtonian fluid. In Newtonian fluids,…

gain further insight into the resolution of this complex disorder, a simplified algebraic model can be constructed to represent the interrupted flow of cerebrospinal fluid. One of the greatest obstacles for…

Fluid dynamics relating to bluff bodies, non-streamlined structures or streamlined bodies at large angles of attack, remains a critical focus of study within the fluid mechanics community. One particular area of interests involves the occurrence of fluid-induced vibrations, or more commonly known as vortex-induced vibrations (VIV’s), exerted on bluff bodies. Due to the production of vortex shedding beyond bluff cross sections, an alternating pressure distribution produces periodic fluctuations…

The topic of mechanic work is so engaging to me that I lose track of time. Just being under the car or truck and looking at the engine. Just being around cars and learning about how they work has made me lose track of time. I love it. Just being able to hear the engine turn over after me and my dad worked on the car, it amazing. I love the feeling. My Dad, my Grandfather, and I worked on my Step-mom's car because it wouldn’t start. It would start with jump starting it. We had to change the…

research into Farm Equipment Mechanics. I have chosen this because I want my career to be Agriculture related. I do not know yet what I want to pursue as a career. I think that I am capable of having a more efficient career. I would like to pursue a more well paid job than what I am researching about. Even, after researching the career of a Farm Equipment Mechanic, i have not decided whether or not I want to pursue this career. Concerning daily tasks, farm equipment mechanics are required to…

A I.T mechanic is a basic component of every office workforce. He/she fixes computers or gets them running. They don’t just do only that. They create systems for the business such as email accounts or a server farm. I.T mechanics aren’t highly appreciated for what they do. But I assure you without a I.T mechanic any business could fall due to something small. Such as a bug or virus that could cause serious trouble. Any I.T mechanic with the correct training could fix any technology related…

Diesel Mechanics Do you have a job career that you enjoy doing? Well I enjoy Diesel Mechanics so I’m going to tell you all about it, what I know, and what I have learned. Diesel mechanics can be a hard and a rewarding job. Diesel mechanics have a large effect on most everything that people do. Diesel technology is very similar to gasoline engine systems, yet diesel is not as popular. Diesel mechanics repair engine in many vehicles and machines that help keep people's lives comfortable. Most…
