of failure is not a universally positive motivator. In some cases it is neither positive nor a motivator. Failure may be described as the eventual and inevitable by-product of the expenditure of efforts to achieve success. A fear of failure has never been anything but an abstract to me, because I do not embrace failure as an acceptable outcome. Success may be attained by researching methods to achieve an action or by avoiding problems through observing failures of other people. In the study of machine tool technology, observance of others failures has benefited me when performing machining operations. Despite careful preparation, failures may still occur through no fault of the machinist. Even a master machinist may kill parts as cutting tools may break, castings may have unseen inclusions, segregation or porosity may cause undetected structural weakness, the forging process may cause cracks in the material, the milling machine or lathe may fail, or work-pieces may slip. Numerous activities may cause failures beyond the control of the machine operator. Machinists and many other occupations do not fear failure because they understand it is unavoidable. Machine shops allow a specific failure rate in the machining process because it is understood they will occur. Thus, fear of something that is inevitable is not useful to success. One need not look farther than the self-help isle at the bookstore to realize fear is negative rather than positive. For example, why…
really misses her. With every clip of her smiling there is a longer clip of him working out or doing something new at the gym. This is when the chorus plays again. This time the couple is in the car and he grabs his bottle of pills while driving. She takes them out of his hand and hands him a card. The person watching cannot tell what the card is for but it is clearly foreshadowing for something. The girl then makes him pull over and she gets out of the car still exasperated. The lyrics as…
syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley packed the particles in a substance are while viscosity is the resistance that a fluid has to flowing and movement. Viscosity is due to the movement of particles. The particle theory is a great tool to help us understand how…
The idea of this investigation came from curiosity that I had ever since I was younger. I questioned why honey had a slower flow than water. This is a liquid’s resistance to flow and that is otherwise known as viscosity. This a concept that people would call thickness of a liquid. It makes sense that the thicker the liquid the viscosity would be greater. Viscosity describes the friction of a moving liquid. A liquid with high viscosity resists motion due to the fact its molecular composition…
Blood Flow as a Casson Fluid 1 THE PROBELM This problem was chosen from Problems for Biomedical Fluid Mechanics and Transport Phenomena section 8, because of my interest in biomedical engineering. How the body works on the most fundamental chemical and physical levels is something that has always fascinated me. This problem, and others in the section on blood flow, offered me a chance to delve deeper into how the body works as well as transport phenomena. The problem gave us a solved velocity…
Objectives With the use of similar apparatus equipment through constant temperature at atmospheric pressure, the viscosity will be determined by tests in two different fluids in sets of two ball trials; along with data collected from a third set. By reducing errors and obstructions it will justify data for better discuss and calculated results, supporting the theory beyond the lab report to resonate in helping others comprehend the experiment. Procedure The experiment was…
starts, and any of my classmates are even awake, I unwillingly go for a quick three mile run. With sweatpants and a sweatshirt on, the long thirty minute run drags on to what seems like forever. As the treadmill slows to a stop, I hop off, wipe away the sweat, and return to the locker room for a shower. I complete my next workout in at practice after school. I need to get a consistent sweat going before practice, so I go for a hard run around the hallways. Once practice starts, dehydration and…
The experiment of fluidization in packed column was determined by using air as the conveying media. The fluidized bed is when the air make the solid to behave like a fluid. For this experiment, two columns are use which one column are filled with sand and the other one filled with aluminum oxide. The bed height of aluminum oxide is 100 mm and have a particle size about 250 micron (mesh 60). The minimum fluidization velocity is used to determine the pressure drop. As mentioned above, when the…
hat cut out could be added to the top of the device to further explore the steampunk theme. This is a rather simple but effective design. One concerning factor about this example is that it appears to be quite thin. I would prefer a chunkier clock with multiple layers. The example is clearly made predominantly using laser cutting…
Computational Fluid Dynamics Computational fluid dynamics (CFD) is the simulation of fluids in engineering systems using modeling such as mathematical physical problem formulation and numerical methods like discretization methods, solver, numerical parameters and grid generation. Computational fluid dynamics is based on the concept of Reynolds averaging of the unsteady Navier-Stokes equation commonly known as (RANS) which are considered by Leishman to be the most adaptable method for…
