1. Raul Colon, Sean Gartland & Dorian Whippie Questions #1-5

2. Question #1 A civil engineer is best suited to: A. Investigate the mechanics of bridges and roads. B. study atmospheric pollutants C. perform pipe stress analysis D. develop a new model of car

3. Answer #1 The answer to question #1 is A (investigate the mechanics of bridges and roads) because a civil engineer is one that that deals with design and construction, and would be best suited to work with bridges and roads.

4. Question #2 When selecting a product solution, the most important factor for an engineer to consider is: A. functionality B. ergonomics C. cost D. safety

5. Answer #2 The answer to question #2 is D (safety) because the most important aspect of a product is its safety, you want to ensure that the consumer isn�t hurt while using your product.

6. Question #3 The first person in history to be credited with inventing the lightning rod is: A. Benjamin Franklin B. Hedy Lamarr C. Isaac Newton D. Mary Anderson

7. Answer #3 The answer to question #3 is A (Benjamin Franklin). He was the first to invent and successfully test the lightning rod.

8. Question #4 The main components of the engineering design process include identifying, defining, selecting, implementing, and: A. deconstructing B. debating C. evaluating D. enhancing

9. Answer #4 The answer to question #4 is C (evaluating). In the Engineering design process evaluating comes after implementing and the other options were not in the design process.

10. Question #5 The relationship of force, pressure and piston area in an air cylinder is represented by: A. pressure = force � area B. force = pressure x area C. area = pressure/force D. force = area + pressure

11. Answer #5 The answer to question #5 is force = pressure x area, because the formula for force is pressure times area or F=PA.

12. # 6 Calculate the flowout of a pipe per hour if there are 180 gallons per minute

13. #7 When specifying and identifying threads, what does the underlined number in �-13UNC-2A represent? B.) Class of fit

14. #8 When a micrometer read 2.468 inches for a hole that is to be bored to 2.473 inches, the hole is considered: 2.473 � 2.468 = .005 D.) 0.005 inches undersize

15. #9

16. #10 Calculate the resulting downtime cost if there ares $3000 in lost production, $500 in spare parts, $250 in re-startup costs, $500 in lost energy costs, and $1000 in depreciation costs.

17. The Venn diagram, is a convenient way to illustrate definitions within the algebra of sets. Consider a Universal set with two subsets A and B. We may represent this as a rectange containing the universal set, with circles containing the elements of A and B.

18. #11

19. Spectrum works left to right

21. Question 15 � x 242=60.5

22. 16 The government organization whose purpose is to set and enforce worksite safety and health standards is A. OPM B. EEOC C. NLRB D. OSHA

23. 16 Answer is D. OSHA which is the occupational safety and health administration OPM stands for office of personnel management EEOC is equal employment opportunity commission NLRB is national relations labor board

24. 17 When storing gas cylinders, it is important that they be stored in A. well ventilated areas B. air tight areas C. cool, damp areas D. a horizontal position

25. 17 Answer is A. well ventilated areas They need to be stored in well ventilated areas. If not a leak could result in and explosion or the gas could asphyxiate someone

26. 18 Surge protectors are installed on electrical equipment to protect equipment from A. sudden power increases B. sudden electromagnetic bursts C. ultraviolet rays D. drops in voltages

27. 18 Answer is A. sudden power increases A surge is a sudden power increase

28. 19 Using Ohm�s law how much current is going through the following circuit? 15.5 volts 5 ohms resistance A. 3.1 amps B. 7.75 amps C. 31.0 amps D. 77.5 amps

29. 19 Answer is A. 3.1 amps Ohm�s law is I=V/R Amps = 15.5/5 Amps = 3.1

30. 20 In the DC circuit below, if R5 burns open, the total current A. increases B. decreases C. remains the same D. goes to zero

31. 20 Answer is B. decreases Due to when you have a series circuit the total resistance is all the resistors added together, but by having a parallel circuit the resistance gets divided so by having the resistor removed or burning open that resistance is no longer dived causing it to be greater and the current to decrease.

32. NOCTI Test Group Leon, Odain, Kris, Chris, Cierra

33. Cierra�s Question # 21. What is the Fahrenheit equivalent for 35 degrees Celsius? A. 87 degrees Fahrenheit B. 95 degrees Fahrenheit C. 102 degrees Fahrenheit D. 115 degrees Fahrenheit Answer: B. 95 degrees Fahrenheit Explanation: The equation for converting Celsius to Fahrenheit is (9/5)xC+32. If you plug in the degrees Celsius (35) for C and do the equation, the answer comes out to be 95. To convert fahrenheit to celsius it is C=(F-32) x 5/9.

34. Odain�s Question #22 A knitting a needle is an example of which type of simple machine. A. lever B. wedge C. inclined plane D. pulley Lever-a rigid bar pivoted about a fulcrum Wedge- any shape that is triangular in cross section Incline plane- a simple machine for elevating objects; consists of plane surface that makes an acute angle with the horizontal Pulley- Rotating wheel, which lifts heavy loads or aid in transmitting power, by use of the belt or cable hat fits into the rim around the wheel.

35. #23 Gauge pressure at sea level is A. 0 psi B. 3.14psi C. 14.70 psi D. 29.40 psi

36. Leon�s Question #24. The binary number 100101 equals: A. 25 B. 37 C. 48 D. 52 Explanation: The number 1 represents a power of two. To find out what a number equals you add the powers of two according to it�s position in the binary number. Answer: 20 + 22 + 25= 1+4+32= 37(B)

37. Christopher�s Question #25. A farad is a unit of ______ A. Capacitance B. Current C. Voltage D. Resistance Answer: A. Capacitance Explanation: The answer is capacitance because the unit for current is the amp, the unit for voltage is volts, and the unit for resistance is the ohm.
