Course Description:

Principle of the design of machine. Design methodology and process in development of machines.

Course Objectives

By the end of the course, you be able to:

Comprehend standard structure/mechanical design methods.
Understand stress and deformation of structural elements.
Understand major mechanical/structural components.
Know machine/structural designs.
Understand numeric finite elements analysis.

Course Requirements:

Attendance – Attendance is mandatory. Lectures, videos, and class discussions will contain vital information needed to do well on the exams.

Required text: David H. Myszka, Machines and Mechanisms-Applied Kinemtaic Analysis, 4th edition, 2012, Prentice Hall, ISBN 0-13-215780-2.

Exams: There will be THREE exams (this includes the final exam). Exams will be based on text readings, handouts, class exercises, videos, and class lectures and discussions. Students are responsible for all text material, regardless of whether we review the text material in class or not.

Missed Exams: You will be allowed to make up a missed exam only if you have adocumented university excused absence. If you know in advance that you will miss an exam, you MUST contact me before the scheduled exam. Make-up exams will not contain the same questions and may contain only essay and short answer questions.

Assignments: Homework will be assigned every Wed; it will be due one week later in class. In solving the homework problems, the following four steps should be followed very carefully:

Briefly summarize the problem statement.
Provide a schematic diagram of the problem.
Solve the problem showing your work in detail by stating your assumptions and providing the equations you used and the numerical values you obtained.
Write a sentence or two discussing your findings.

Grades will be based on:

Attendance 5%

Homework and Quiz 20%

Two Midterm Exams 20% each

Final project 10%

Final Exam 25%

Grade Distribution

90-100 = A

80-90 = B

70-80 = C

60 - 70 = D

Below 60 = F

Disabilities Accommodation:
