Mag Lev Vehicles Case Study #2“Magnetic Levitation Transportation” Northern Highlands Regional High School Applied Technology Department Real World Engineering List Design/Build Engineering Team Members Name of Engineering Firm Date – 1/5/15 Instructor- Ms. Sicola
Scenario • Your Engineering Firm has been approached by the New York State Transportation Authority to Design and Build the World’s Fastest Transportation System. • The vehicles must travel between New York City and Washington DC as fast as possible in the shortest amount of time.
Statement of the Problem • The problem we had to solve was to design and build.the world’s fastest mass transit mag-lev vehicle that will travel between two designated points in the shortest period of time.
Design Criteria • The vehicle must use magnetic levitation as the means of reducing friction. • The vehicle prototype can measure only 2-1/2 inches wide and have a maximum length 7.75” long – minimum length of 6”. • The vehicle will use a powerful electric motor and propeller(s) as the means of propulsion. • The vehicle must travel down the length of a 15’foot track in the shortest amount of time.
Design Constraints • You must use only the materials supplied by the teacher to construct the mag-lev vehicle. • The body of the vehicle must be constructed of one piece of Styrofoam that measures 7.75 inches long by 2-1/2 inches wide by 2 inches in height.. • The Styrofoam can be cut and shaped anyway possible to create a sleek, aero dynamic vehicle body. • The base of the vehicle will be constructed of a 3/16 inch thick piece of foam core board . • Each Design/Build team will receive per (each) vehicle: rough stock foam measuring 2-1/2x7-7/8 x2, foam core board measuring 3/16 x 8 X 2-7/16, 6 magnets, one 9 volt DC high speed electric motor (5,000 rpm), a propeller, red and black electric wire, solder and hot glue. • Each Engineering Team will have ~8-10 class periods to design, build and test the final solution to the mag-lev vehicle.
Possible Solutions Theory on how it will work: Prototype #1) Prototype #2) Prototype #3)
Possible Solutions Results of tested runs: times and explain how it performed • Prototype #1 Run 1: Run 2: Run 3: • Prototype #2 Run 1: Run 2: Run 3: • Prototype #3 Run 1: Run 2: Run 3:
The Final Solution – Speed • Description of the Final Design: Time#1: Time#2 Tine#3
Test Results and Conclusions COPY QUESTIONS INTO WORD AND ANSWER • Did your design solution meet all the design criteria and stay within the design constraints? • If the answer is NO, what did you have to change in either the design criteria or constrains? • What was the total mass that your mag-lev measured in grams? • Explain how each of your mag-lev vehicle designs incorporate the principles of balance and center of gravity? • Describe what your team observed when testing each group members prototype design solution. • Describe in a few sentences what your Design/Build Team would do differently with the final solution in order to make it perform better. • How did your final design solution (mag-lev) compare to the other mag-lev vehicles tested and built in class? • Explain in a paragraph what your team found the most difficult part(s) of this case study? • What was your fastest time recorded out of 3 attempts? • Create a line graph comparing the times for your final 3 attempts? • Create a line graph comparing the weights (grams) for all the Design/Build Team’s maglev vehicles? • Create a bar graph comparing the fastest times for all the Design/Build Team’s maglev vehicles? • Create a bar graph comparing the average times for all the Design/Build Team’s maglev vehicles • What was the calculated speed of your vehicle in Feet/Second for each of your final 3 attempts? • What was the calculation of your vehicles in M.P.H for each of your final 3 attempts? • Do you feel that Magnetic levitation vehicles and trains are a possible solution to our energy and transportation problems? Why? • Each group member write a 2 paragraph evaluation of the project explaining likes, dislikes, was it interesting, fun etc. Write your names at the beginning of the evaluation. • CAD Drawings – each group member will produce a 2 view drawing of their final solution/prototype
Grading Breakdown • Research Paper – 80pts • Working Model Vehicles – 120pts (each group member’s car to receive its own grade) • 45pts Fastest timed run according to the rubric • 45pts Average time of all 3 trial • 30 pts individual – fastest time and average of time trail – 15pts each • Final Vehicle – 120pts • 45pts Fastest timed run according to the rubric • 45pts Average time of all 3 trial • 30 pts individual – fastest time and average of time trail – 15pts each • Possible Solution CAD drawings – 100pts • Documentation – 120pts • CAD Drawing – Final Solution 100pts • Presentation – 100pts • Meeting completion deadline dates – 15pts each
