Internal consistency

amount of chromium that stainless steel contains, the stainless steel will form a chromium oxide film which will help prevent corrosion as it blocks the oxygen fusing to the surface of the steel and in turn blocks it from spreading to the steels internal structure. Whereas in general…

Q1: Assume that all probabilities and outcomes are accurate and certain. First, there is a decision, which is whether we need Geo-Star to provide consultation. If we need the consulting, we have to pay them $0.1 m + 10% of the total uranium found. After we choosing Geo-Star, the company will provide two reports, favourable (60%) and unfavourable (40%). For favourable report, we can choose dig or not dig. If not dig, we will lose totally $ 0.1m. if dig, 90% get substantial amounts of uranium 25…

Toyota Prius: The Toyota Prius started as a car model in 2000 but is now a sub brand of Toyota. At least in my mind it was since I own a Plug-In and thought I had read that Toyota was making it its own little brand. But to my surprise Toyota includes the Prius line up (Hybrid (original), V (Versatile – larger like the first minivans), c (City – shorter to fit into those hard to find curb parking spots in urban areas) and Plug-In (Hybrid with 4.4 KwHr battery for 10 miles on battery only) under…

The motorcycle battery is obviously important, well duh, you can’t start a motorcycle without it, so it is important. However, it is probably the most neglected part of the motorcycle as well because it is slightly difficult to reach and take care of it because of its location. So it is quite frequently the battery which is a cause of breakdown of a motorcycle and this is what makes it important for the battery to be maintained properly. Considering the importance of motorcycle battery it is…

The NOx Problem 1. History of Diesel The diesel engine is a Compression Ignition (CI) Internal Combustion Engine (ICE) that was invented by Rudolf Diesel, a German engineer in 1892. Unlike a Sparked Ignition (SI) engine, Diesel designed the engine to run on vegetable oil, more specifically peanut oil. 2. CI vs SI, the difference As its name suggests, the CI engine’s ignition of the air-fuel mixture is caused by the mechanism compression rather than a spark from a spark plug of SI engine. This…

4.5 Non-motorized transport Cities are increasingly turning to the use of non-motorized transport because of the benefits it brings to the environmental and economic aspects. Today, for a variety of reasons (health, environmental, financial, and others) cycling is increasingly popular, and is the most outspread and effective form of non-motorized transportation. The bicycle originated in Europe in the 19th century as a mean of recreation and since then has spread worldwide. The concept has not…

Robert Fulton was an American engineer and inventor in the 1800s. He is best known for successfully creating the commercial steamboat, “The North River Steamboat of Clermont.” What some do not know, is that he was also a painter, a canal engineer, a philosopher. Although Robert Fulton did not invent the steamboat, his participation in developing new machines for naval warfare was more significant than his involvement with “The North River Steamboat of Clermont.” In fact, some may say that he was…

Quality Tools Case Study: Old Sarge Autobus II Fuel Cell Project Question 1: What Quality tools and concepts would your team use to find the root causes for the frequent maintenance? The Old Sarge Strategy Council program was launched to study and reduce, or eliminate the problems faced by customers and bus operators due to frequent maintenance to the fire/explosion suppression system that prevents fuel cells from exploding if struck from the rear by another vehicle. Consequently, the…

Introduction A vehicle becomes hybrid when it combines two or more power sources. In fact many people have probably owned a hybrids vehicle at some point. Hybrid vehicles are powered by two energy sources such as a combustion engine or fuel cell. These are the vehicles having the potential to be two to three times more fuel- efficient than conventional vehicles .In general hybrids capture energy lost during braking and return it to the on-board battery. Hybrid vehicle operates the alternative…

Electric Cars vs. Gasoline Cars – Which is Better? In the late 1800s, a new invention would change the way we travel and transport materials: the car. About 95% of American households own a car, but only around 85% of American households possess a computer, which can be astonishing considering the costs of the two commodities. Moreover, this is likely due to the importance of cars in modern societies. However, an ongoing debate exists about the proper fuel resource that should be used to run…
