Final Report Format/Grading[PDF]

Reverse Engineering Report, Assigned 4/26/13, Due 5/3/13 [FORMAT]

It is taught in a studio format, where a combination of lectures and in-class exercises will be used to develop concepts in statics, energy, and measurements.

Office Hours: Tuesday, 8:30 to 9:30, Thursday, 2:00-2:30 (either EIT 522 or EIT 224)

Homework

Homework #1: vectors, Assigned: 1/28/13, Due: 2/1/13

Homework #2: more vectors, Assigned: 2/12/13, Due: 2/22/13

Homework #3: unit conversions , Assigned: 3/1/13, Due: 3/8/13

Homework #4: forces, Assigned 3/19/13, Due: Thursday, 3/28/13, From Wickert and Lewis, 3rd edition (2nd edition in parentheses), 4.3 (Ch3 Problem 3), 4.5 (Ch3 Problem 5), 4.8 (part a only) (Ch3 Problem 8)

NOTE: all of these problems are just adding vectors and resolving them into x,y components.

Homework #5: moments, Assigned 3/29/13, Due: 4/5, From Wickert and Lewis, 3rd edition (2nd edition in parentheses), 4.12 (part b only) (Ch 3, Problem 12), 4.13 (Ch 3, Problem 13), Problem 4.14 (Ch 3, Problem 14), 4.16 (Ch 3, Problem 16)

Report #2 (heat engine was the first): Assigned: 3/19/13, Due: 4/5. Each group member should summarize the problems that you envision you will have to solve on your bridge design. Base this on the brain-storming output that we developed on Friday, 3/15. This should be no more than 1 page and it will count towards your bridge design grade.

Homework #6: statics, Assigned 4/5, Due: 4/12, From Wickert and Lewis, 3rd edition (2nd edition in parentheses), 4.21&4.22 (Ch 3, Problems 21 & 22), 4.23 (Ch 3, Problem 23), 4.27 (Ch 3, Problem 27), 4.28 (Ch 3, Problem 28) … Quiz 5 on 4/12 will cover this material.

Bridge Design

Students will design a bridge using popsicle sticks, cable ties, duct tape, and string. The bridge will have to span a 5 foot span and survive Wolfgang driving across it. Support will be four cinder blocks, so approach and exit need to be included in the bridge design.

Bridge Groups:

1: Christian Potts, Colton Haney, Jarrett Wemette, Brandi Sadler, Andrew Hegg

2: Lance Lippig, Zacc Danurand, Joshua Shaw, John Williamson, Evan Hartzell, Manahy Alessamy, Max Love

3: Abdulelah Al-Noaim, Joshua Mullens, Demetric Dixon, Corey Burleson

4: Kyle York, Hunter Dunne, Rebecca Rainwater, Mark Johnson, Phillip Portoni

5: Katelyn Glover, Hunter Bell, Nick Butterfield, Brody Bergmanis, Kyle McCraw, Caleb de la Paz

6: (Prestige World Wide) , Ryan Stanley, Ryan Donahue, Lena Burkett

We will discuss reverse engineering and reverse engineer a real mechanical system, such as a manual transmission clutch.

Quizzes

Quiz #1 on Chapter 1 (Introduction) of 3rd Edition of Wickert, Lewis, Introduction to Mechanical Engineering

Quiz #2 on Chapter 2 (Mechanical Design) of 3rd Edition of Wickert, Lewis, Introduction to Mechanical Engineering

Quiz #3 on Chapter 3 (Units) of 3rd Edition of Wickert, Lewis, Introduction to Mechanical Engineering and vectors, 3/1/13.

Quiz #4 on Chapter 4 (Forces) of 3rd Edition of Wickert, Lewis, Introduction to Mechanical Engineering and unit conversion, 3/8/13.

Quiz #5 on Force Calculations, 3/22/13.

We have started building a Stirling Engine.  We should complete the engine by March 1.  The report will be due the following week, and its format and grading are contained in this document.

This week (starting 1/21/12), we’ll be constructing testers to determine relevant parameters of the popsicle sticks and joints. Each meta-group will build a tensile tester and a three-point bender out of Vex parts.
