MIE 313: Design of Mechanical Components

INSTRUCTOR: Professor James R. Rinderle, ELAB 207c, x5-5901

Office Hours: Immediately following class on Tuesdays, Wednesday between 4:15-5:00 and by appointment. Any variations in office hours will be announced in class. I read my e-mail frequently. Address e-mail to rinderle@ecs.umass.edu

COURSE CONTENT

In this course we will study the design of mechanical components , such as springs, screws, bolted joints and shafts as well as the design of systems which incorporate these types of components. We will consider functional, and to a lesser extent, manufacturability criteria by which a design is evaluated. We will also elaborate on the mechanisms of failure, including fatigue. Throughout the course we will seek to develop insight based on analysis of components to aid us in the synthesis of alternative designs and design refinements.

COURSE MEETINGS

The course will meet in Elab 306 on Tuesdays and Thursdays from 8:00 to 9:15 as scheduled. Discussion section meetings will be arranged and announced during the lecture period. Any schedule adjustments will be announced in class. If you do miss a class be sure to ask a friend about class announcements concerning schedules, exams, homework etc. You are responsible for all class announcements.

I will greatly appreciate it if you will arrive at class meetings on time.

BOOKS

The course text is Fundamentals of Machine Component Design by Robert C. Juvinall and Kurt M. Marshek. Alternative treatments of the material can be found in many machine design texts including ones by Shigley and Spotts. Supplemental material will be distributed in class. We will also employ, to a more limited degree, Engineering Design and Design for Manufacturing by John R. Dixon and Corrado Poli. This book is currently the required text for both ME 313 and ME 375.

EXAMINATIONS

There will be three examinations during the semester and a final examination during the final exam period. One or more of the examinations will likely be scheduled during the evening to allow more time than is available during the regularly scheduled class. Please reserve the evenings of Thursday March 28 and Thursday April 18 from 6:00 to 9:00 p.m. for exams. If you have a conflict with either of these dates, please inform me prior to February 6, 1996 so that an alternative schedule can be arranged. Exam dates, times, locations and format will be announced in class one week in advance of the exam. Make-up exams will not be given except in the most extreme circumstances because of the infeasibility of providing a truly fair and comparable make-up exam.

HOMEWORK

As with most courses and other endeavors, deep understanding and mastery will be achieved only with practice. Therefore, homework will be assigned. Although the homework will constitute only a minor portion of the course grade, experience has shown that those who do not complete the homework usually do poorly on examinations and project work. Homework solutions will be made available to you as an educational supplement. You should review the solutions to familiarize yourself with alternative approaches and to understand the nature of your own errors.

Although we will emphasize concepts, the practice of engineering requires that the concepts be applied carefully so that our designs work and so that our analysis is correct. Your efforts in obtaining valid results will constitute a significant portion of credit on tests and, therefore, should concern you on homework assignments.

Homework will not be accepted late. Homework is offered principally to facilitate learning. Cooperation among students can be an important mechanism for learning and is therefore encouraged. For that reason, homework assignments are graded principally on effort. Nevertheless, submitted work must reflect the individual efforts of the student. Students are allowed and encouraged to work together on homework assignments, to discuss solution approaches and methods but final problem solutions must be worked individually. The use of substantially similar problem solutions from solution manuals or from class materials used in previous years also violates the sprit and the letter of the individual effort requirement. In all cases of cooperative effort and reliance on existing problem solutions, students must state on the first page of any submitted work, the names of cooperating individuals and the source of related problem solutions.

PROJECT

Each student, as part of a group, will be required to complete a project involving the analysis and redesign of an actual mechanical device. Written project reports will be due on Monday May 13, 1996. Oral presentation of projects will be made during the evening of May 14, 1996. Please reserve this date and notify me of any conflict prior to February 6, 1996. More specific project requirements will be discussed in class.

GRADING

• Homework 10%
• Project 25%
• In class exams 40%
• Final exam 25%

COURSE POLICIES

* All assignments, projects and examinations must be completed on time. Make-up exams will not be given. Exceptions will be made only in extreme circumstances.

* You should retain all graded work until the course grade is given.

* All provisions of the Department and University policies regarding academic honesty will be enforced including those provisions which apply to homework. You are responsible for knowing and adhering to these policies. University policies can be found in the booklet Undergraduate Rights and Responsibilities. A copy of The Mechanical Engineering Department Academic Honesty Policy can be obtained from me or by typing on the ECS Vax system COPY D$USERS1:[PASCOE]HONPOL. *.*
