The equation for solving the Volume of a Cylinder is a simple middle school equation: V= πr2h, where h = height and r= radius. The equation can also be written in “multi variable form: f(r, h)=πr2h. This allows us to work with partial derivatives if either h or r are held constant. The most […]
The factor that determines whether a material is a conductor, semiconductor or insulator is the amount of free electrons it has. For example, a silicon lattice has no free electrons because they’re all bonded to one another. This makes it an insulator. Copper has free electrons in a pure state, making it a great […]
Materials that conduct electricity/current on an atomic level, are materials that have free electrons that are able to move from atom to atom due to small distances between each atoms outer electron band. In turn, electricity/current is able to flow throughout the material without much effort. Common conductors would be copper, aluminum, gold, and […]
Part 1: This includes an Excel spreadsheet that performs specific calculations. The Insurance Institute for Highway Safety, IIHSLinks to an external site., states on their site that “Providing adequate yellow signal time is important and can reduce crashes. Studies have shown that increasing yellow timing to values associated with guidelines published by the Institute of […]
I chose to look at “Making Changes to the work of another Engineer”, Case No. 09-6. I chose this subject because it is something I deal with daily at work and wanted a better understanding of the issue so as to avoid ethical issues in the future. The question presented in this Case was, […]
The topic I chose was, “Why Can’t This Soap Dispenser Identify Dark Skin?” The subject is how sensors within things like soap dispensers, paper towel rollers, etc. can’t see a person’s light reflective characteristics because their darker skin absorbs more light than a fairer person. I do not believe there are any ethics violations presented […]
I looked up the article “Making Changes to the Work of Another Engineer” this article talk about 2 Professional Engineers working on the same project together. The problem comes when one engineer tries to revise another engineer’s work. Section II.2.b of the NSPE code of ethics says that you cannot sign for any documents that […]
Pilot 1 and 2 plan to meet at the world’s largest rock. Pilot 2 has to fly 19 miles at a 45 degree angle. Pilot 1 has to fly at a 100 degree angle to get to the rock. How far is pilot one from the rock and how far is it between the two […]
o, I am again going to discuss using the SIN function for calculating height with two known variables. The length of a shadow cast from a building and the calculated angle from the top of the building to the end of the shadow. In this case Length = 70m and = 75 deg. In Mathcad […]
I chose the topic of rethinking electronic education. Learning electronics through projects is a great idea for getting students to learn. Being enrolled in school and this particular class gives me a sense of wanting to understand what electronics is all about. Learning circuitry and electronics and getting hands-on experience is a great help. […]
