| Textbook: | Machine Elements in Mechanical Design - 4th Ed. by Robert L. Mott | |
Course Description: The methods developed in statics, dynamics, and strength of materials are applied to the selection of basic machine components.The fundamental principles required for the selection of individual elements that compose a machine are developed. Selected course topics are included as computer exercises.
Goals/Objectives:
1.Developed the ability to apply the principles and methods previously developed in statics, dynamics, and strength of materials to the selection of machine components.
2. Developed applicable refinements of previous analytical skills from mathematics and MET prerequisite courses as utilized in new areas of application.
3. Developed new or more intensive problem solving skills to the course topics.
4. Learned terminology and facts related to covered topics and use them in formulating appropriate problem solutions.
5. Learned concepts and theories which underlie the development of covered topics and use the understanding thus gained to select appropriate solution methods for specific problem solutions.
6. Developed skill in using, reading, and interpreting necessary materials such as tables, charts, graphs, and industrial catalogs as a part of appropriate problem solution.
7. Demonstrate skill in and a commitment to accurate work by applying appropriate formulas to problem solutions in conjunction with an appropriate utilization of variable lists and appropriate variable units..
8. Synthesized previously learned computer skills with select course topics to develop problem solving computer software.
Course topics and lecture hours devoted to each topic:
Note: The class is divided into three distinct sections:
Part I focuses on reviewing and upgrading readers' understanding of design philosophies, the principles of strength of materials, the design properties of materials, combined stresses, design for different types of loading, and the analysis and design of columns.
Part II is organized around the design of a complete power transmission system, emphasizing the interrelationships among machine elements in addition to their unique characteristics. Included are belt drives, chain drives, gears, shafts, keys, couplings, seals, rolling contact bearings, and completion of the design of a power transmission.
Part III presents methods of analysis and design of plain surface bearings, linear motion elements, fasteners, springs, machine frames, bolted connections, welded joints, electric motors, controls, clutches, and brakes.1. The Nature of Mechanical Design (1 class hour)

Note:
It is important that you have read the assignments for the day before coming to class. Lectures and presentations all relate to the general topic of the day’s assignment, but all of them are not directly from the book. Lectures will highlight important concepts and present additional material. Discussion of critical issues is an important element of the course. Discussion of current events will be used to provide a “real world” reference for the fundamentals covered in this course. Test and quiz questions can come from reading and/or lecture.
Combined Tests/Examinations: 40% Tests will include problems and short answer questions.
Homework/Quizzes/Extra Credit: 35% Homeworks will be assigned each week.
Final Exam: 25%
