Exam Attendance Slip I, the undersigned declare that I attended this exam Student ID Number: Student Name: Student Signature: THIS PAPER CONTAINS 7 PAGES INCLUDING THIS COVER SHEET TRUE/FALSE QUESTIONS [5 Marks, 0.5 for each item] Please state whether the following statements are true or false. Item Statements 1 Engineers do need a license to practice engineering. 2 Technicians work closely with engineers and scientists to accomplish specific tasks, e.g. laboratory procedures. 3 4 Not all moral values are standard throughout the world. 6 Ethical egoism is a moral theory that is based on the best interest of the society not individuals. 7 The ability to logically break down a problem into pieces is called reductionism. 9 10 False √ √ Concurrent engineering is an old fashion way of dealing with engineering projects. The first step you should take when designing any engineering product is to assemble a design team. 5 8 True Research problems occur when equipment behaves in unexpected or improper ways. When structuring your writing or speech, a problem-to-solution strategy describes the advantages and disadvantages of a particular approach. A combination of an oral presentation with strong visual aids leads to a much higher retention rate by the audience, even days after the presentation. √ √ √ √ √ √ √ √ MULTIPLE CHOICE QUESTIONS [6 Marks, 0.5 for each item] 1.

You have an accountant friend Sara who is working in and engineering company X. She tells you that her daughter is extremely ill and that she must have an operation to survive. She also tells you that she has no insurance and the operation will cost QAR100,000. One week later, you ask Sara about her daughter and she tells you that her daughter is just fine now. She then tells you secretly that she took QAR100,000 from an account of the company to pay for the operation. She assures you that she has already started paying it back and will continue to do so until it is all returned. A-) What is the ethical violation in this case? [ 0.5 p] She violates engineering code of ethics by taking company’s money. The ethical violation is “stealing” since she did not get the permission before taking the money. B-) What do you do? [ 0.5 p] Choice 1: Inform the authority about this Choice 2: Keep quiet C-) Justify your answer. [ 0.5 p] Justification for choice 1: As per engineering code of ethics, I am required to inform this to the authority. Justification for choice 2: Strictly speaking although unethical, I keep shut on compassionate ground. 2. Explain five things that you can do during your presentation to overcome your nervousness[1.5p] A-) Tell a joke or use an anecdote B-) Try to memorize the first few sentences so you can deliver them in an “auto-pilot” mode C-) Try to look at the people who are friendly, not bored or disinterested D-) Be well prepared E-) Allow yourself to make mistakes 3. Mention five types of visual aids that engineers use in their presentations [1.5 p] A-) Tables B-) Word Charts C-) Photographs D-) Schematics E-) Maps, Videos, Animations etc. 5 4. One of the major steps in engineering design method is to identify constrains and criteria for success. List down five typical constraints. [1.5 p] 1. Budget 2. Time 3. Personnel 4. Legal 5. Competition 5. Describe any five traits of a successful engineer. [1.5 p] 1. Interpersonal Skills 2. Communication Skills 3. Leadership 4. Competence 5. Logical Thinking 6. What does the engineering team consist of? [1.5 p] A-) Scientists B-) Engineers C-) Technologists D-) Technicians E-) Artisans 7. What is the difference between “Sequential Engineering” and “Concurrent Engineering” ? [1.5 p] In sequential engineering, each engineer or specialist work separately in his assigned task to find a local optimum for each step so they missed the global optimum. While on concurrent engineering, engineers (specialists) work together right from the beginning to find a global optimum. 8. A-) Define etiquette? [0.5 p] Etiquette consists of codes of behavior and courtesy. B-) Define law? [0.5 p] Law is a system of rules established by authority, society or custom. C-) Write 2 key differences between them [ 0.5 p] 1. Unlike etiquette, violations of law carry penalties. 2. Unlike etiquette, law is established by authority such as governments etc. 6 9. Estimate how many trucks needed to move dirt from a piece of land that is 40 m width x 40 m length x 5 m depth using an average size construction truck? You must show all your calculations. [ 1.5 p] One average size construction truck is approx.= 2.5 m wide x 1.5 m tall x 5 m long ( cargo bed of a truck) Number of trucks = (Volume of dirt) / (Volume of a truck) 3 3 Number of trucks = ( 40 x 40 x 5) m / ( 2.5 x 1.5 x 5) m Number of trucks= 427 trucks 10.
