Properties and applications of Materials Assignment 2 Task 1 (P1) I. Describe the structure including the atomic structure of the element copper. Copper has a symbol Cu. It is a metal with a very high thermal and electrical conductivity. Pure copper is soft and malleable when it is freshly exposed the surface has a reddish-orange colour. It has an atomic mass of 63.546 g.mol -1 and an atomic number of 29. The electrons per energy level for copper go 2‚8‚18‚1. Copper has an atomic number of 29‚ thus

the system employs 25‚000 persons‚ who manage 28‚000 coaches. The Dutch railways needed a new information system that would manage the information displays and all audio broadcasts across all the stations. These systems would be automated‚ and give updated information to passengers about train arrival and departure times‚ destinations‚ and station and track locations. The systems would run independently of manual intervention‚ basing their displays and announcements on information retrieved from train

Building the Boeing 787 1. What are the benefits to Boeing of outsourcing so much work on the 787 to foreign suppliers? What are the potential risks? Do the benefits outweigh the risks? Benefits: * Outsourcing the state-of-the-art electronics on the flight deck and in the passenger compartments allowed Boeing to reduce the risks associated with this technological gamble; * Boeing was able to negotiate $8 billion in development costs from the partners in return for a share of

1. Why is Airbus interested in building the A3XX? What are its objectives? Airbus predicts that there would be demand for more than 1500 super jumbos over the next 20 years that would generate sales in excess of $350 billion. And they could sell as many as 750 over jumbos over the next 20 years with a break even on undiscounted cash flow basis with the sales of only 250 planes. There is a huge profit in this business if Airbus succeeds in the industrial launch of A3XX jumbo jets. In addition‚

1. Can you explain the PDCA cycle and where testing fits in? Software testing is an important part of the software development process. In normal software development there are four important steps‚ also referred to‚ in short‚ as the PDCA (Plan‚ Do‚ Check‚ Act) cycle. Let’s review the four steps in detail. Plan: Define the goal and the plan for achieving that goal. Do/Execute: Depending on the plan strategy decided during the plan stage we do execution accordingly in this phase. Check: Check/Test

Introduction For this assignment‚ I chose the American multinational corporation Boeing (The Boeing Company) which is one of the largest aircraft and aerospace manufacturer in the world. I thought that it would be a good idea to take Boeing as it has been into some media frenzy recently‚ because of its latest commercial aircraft the 787” Dreamliner” grounded by Federal Aviation Administration (FAA) and aviation authorities around the world. A good case to see how a company future assets valuation
