Field

decreased, but technology has increased. With the new satellites, the earth can be scanned once every 24 hours. This information can be made available to the public for various studies. There is much that can be done in the mechanical engineering field. Truly the sky is the…

sugar-induced hysteria. All five cradled ice cream cones, exuberantly embracing each other with sticky hands. Crisp pine trees lined the path through camp, framing the elated chaos. With a click, I stopped down the aperture, extending the depth of field and drawing each member of my wacky sixth grade group into focus. Hitting the shutter, I captured my composition of carefree elation. Although I created this image within a fraction of a second, the joyous frenzy it encapsulates took a week to…

magnets are the most common ones. Once they are magnetized they stay so (although they can lose much of their magnetic force). They can be metals found in nature. Temporary magnets hold the properties of a magnet while in a magnetic field, but lost these properties once the field goes away. An example of this would be a paper clip that is charged and can act as a magnet for a limited time. Electromagnets are wires wrapped around a metal center (usually iron). The wires have a current flowing…

To gather information about mechanical engineering, I interviewed Graham Jessup, a graduate from the University of Washington and a mechanical engineer at Electroimpact Engineering; a company based in Mukilteo Washington. Electroimpact is a world leader in design and manufacturing of aerospace tooling and automation. During the interview that took place through several emails, I learned much about what mechanical engineers are required to know, and how they use that knowledge to fully accomplish…

spin. This spin is then determined by its quantum number, which is represented by the symbol S. Each nuclear spin is associated with a magnetic moment. When this moment is placed in an external magnetic field, these spin states differ in magnetic potential energy. If placed in a static magnetic field with a small amount of spin polarisation however, certain radio frequency signals can allow a transition between spin states, with some of the spins being placed in a higher energy state. When the…

The main actors in the movie are Tom Hanks portraying Forrest Gump, Robin Wright portraying Jenny Curran, and Sally Field as Ms. Gump. The actors did a good job of acting like southerners in the movie, and they didn’t play out of character; However, there are a few goofs in the movie. As Forrest in the scene where he takes apart his gun and reassembles it, Hanks forgets to use his accent for a few seconds. There are also more mistakes in the movie that no one has seemed to notice. If someone was…

Results An initial resistance versus magnetic field measurement on NdMo16O44 reveals a pronounced magnetic hysteresis effect when a magnetic field is applied perpendicular to the current, but with unknown orientation with respect to the crystal axes, as shown in Fig. 2a for temperatures from 12K to 30K (at temperature below 12K, the overall resistance is too high to produce low-noise measurements with resolvable magnetoresistance features). The individual plots are offset to better show the…

average. This increase is due to the fact there is an increase in demand for faster, less expensive, and more efficient technologies” (“Labor Market”). Although being a mechanical engineer doesn’t pay the highest people tend to acquire jobs in this field in order to keep advancement in technologies flowing. “Electrical advances keeps employment high and the development of new devices is necessary for advancement” (Texas Workforce Commission). The development of new technologies opens many job…

experiment demonstrates the laws very well, however, it is not particularly useful for a comprehensive investigation as the magnet is out of view whilst in the tube. Lenz’s law can also be demonstrated through passing a metal sheet through a magnetic field and observing the slowing of the metal sheet, however, there are limited results from this experiment as the resources aren’t readily available. One of the benefits from this investigation is that the magnetic braking force acts continuously…

variable frequency eddy current sorter (VFECS) prototype to separate different nonferrous metal and alloy of size smaller than 1 inches. VEFECS is a solid state technology which operates at variable high frequency range between 1 – 10 KHz. The magnetic field frequency plays an important role in sorting of different nonferrous metals and alloys from each…
