ME311Syllabus2014.doc Fairfield University School of Engineering Syllabus for: Machine Design, ME311 Instructor: Prof. William Dornfeld Contacts: [email protected] Daytime phone: 203.761.4325 (Best Noon to 1PM) Evening phone: 203.438.9715 Course Web Page: http://www.faculty.fairfield.edu/wdornfeld/ Instructor Assistance: One Half Hour before or after every class, or by appointment Lecture Hours: 6:30 to 9:00 PM Thursdays Class Requirements: 1) Completion of ME308 (Strength of Materials) is a prerequisite for this course. 2) Assigned homework will be discussed at the following class session - students will present their solutions at the beginning of the session. 3) Oral and written reports will be required for the reverse-engineering projects. Course Description: Fundamentals of mechanical engineering design are applied to analyze, design, and/or select components typically used in the designs of complete mechanical systems. Part 1 of the course covers the design process and analysis of stress and deflection. Part 2 includes material properties and loadings (steady state and variable) as they relate to failure prevention. Responsible design (safety factors and ethics) will be addressed. Part 3 covers the procedures for design and analysis of common machine elements such as columns, cylinders, fasteners, and springs. In team “reverse engineering” (R-E) projects, students will apply the course topics to real hardware. Computer techniques including MSExcel with Visual Basic Applications will be emphasized. Course Learning Goals Expected Outcomes 1. Students will learn the stress and strength aspects of machine design. a. Ability to correctly analyze loaded structures. b. Ability to select correct material strength properties. 2. Students will learn how to determine the limiting loads and deflections in mechanical components. a. Demonstrate ability in reverse engineering project. 3. Students will learn the characteristics governing the application of typical machine elements. a. Use appropriate engineering data to select and size machine elements. 4. Students will develop their oral and written communication skills. a. Generate professional quality R-E project report. b. Deliver oral R-E presentation. c. Explain homework solutions to class. 5. Students will learn to apply computer techniques to design analysis and to use the Web to obtain design information. a. Use computing tools to solve homework problems and in reverse engineering project. 6. Students will learn to function in team situations. a. Demonstrate teamwork in R-E projects. 7. Students will learn professional and ethical responsibility. a. Ability to understand and apply safety margins. b. Ability to identify and manage design dilemmas.ME311Syllabus2014.doc Schedule: Session Topics Reading (Before Class!) 1 4-Sep-14 Introduction - Fundamentals of the Design Process, Review of Stress, Units, Mohr's Circle Chap. 1; Chap. 2 But Not 2.8.3, 2.11, & 2.17-2.18 2 11-Sep-14 Materials - Strength & Other Properties, Stresses & Strains, Power Transmission Chap. 3 But Skim 3.3 & 3.7 - 3.8; Chap. 4 3 18-Sep-14 Review of Deflection, Strain Energy Methods Chap. 5 But Not 5.3 & Skim 5.5-5.6. 4 25-Sep-14 Stress Concentration; Steady Loading - Failure Theories Chap. 6.1-6.2, 6.6-6.8 5 2-Oct-14 Review; Take-Home Exam Distributed 6 9-Oct-14 Variable Loading - Fatigue, Modifying Factors; S-N Curves Chap. 7.1-7.9 7 16-Oct-14 Take-Home Exam Review; Fluctuating Fatigue; Impact 7.10 -7.10.1 (Except Complete Modified Goodman Diag.), 7.13-7.14 8 23-Oct-14 Review; Columns & Buckling Chap. 9 9 30-Oct-14 Cylinders & Press Fits; Disks Chap. 10 (Skim 10.2) 10 6-Nov-14 Power Screws; Bolted Joints; 2nd Take-Home Distributed Chap. 16.1-16.4, Skim 16.5 11 13-Nov-14 Mechanical Springs – Stress & Deflection Chap. 17.1-17.4 12 20-Nov-14 Exam Review; Spring Fatigue; Torsional Springs; Rev.Engr.

Students are responsible to acquire notes and homework assignments from classmates in case of absence, and to notify the professor. The course will be graded as follows: The seven characteristics of highly successful ME311 students: 1. Complete textbook readings before class. 2. Complete all homework assignments. 3. Ask questions when something isn't clear (for class, homework, & exams). 4. Draw good sketches, show all steps, and apply sanity checks to their work. 5. Search the Web for tutorials and component information. 6. Be a team player in the Reverse Engineering projects and in-class activities. 7. Apply computer techniques to class material, but not instead of hand calculations. Midterm Exams (2) 40% Final Exam 30% Rev. Engr. Reports (Oral & Written) 20% Homework / Participation / Quizzes / Professionalism 10% 1. All students should review the Academic Honesty section of the Undergraduate Course Catalog to understand what conduct to avoid and what bad things happen when that conduct is not avoided. 2. Students who have arranged for special accommodations through the Office of Student Support Services should present a letter from that Office confirming their need for special
