Course Description:

Principle of the design of machine elements. Theory to prevent the failure of mechanical components.

Course Objectives

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

1. Know the concepts from mechanics of engineering and the design of mechanical devices.

2. Understand the design process, material and processes, and stresses associated with loading a

structure.

2. Understand the failure theories associated with design of new components.

3. Know the general engineering principles of independent design and components that are part of a

power transmission

Course Requirements:

Attendance: Attendence is mandatory. Lectures, videos, and class discussions will contain vital information needed to do well on the exams. Be on time, three “late” arrivals will result in one “nonattendance”.

Required text: Wilson, Charles E., Computer Integrated Machine Design, Prentice Hall, 1997, ISBN 978-002-428390-0

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.

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

  1. Briefly summarize the problem statement.
  2. Provide a schematic diagram of the problem.
  3. Solve the problem showing your work in detail by stating your assumptions and providing the equations you used and the numerical values you obtained.
  4. 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 5%

Final Exam 30%

Grade Distribution

90-100 = A

80-89 = B

70-79 = C

60 - 69 = D

Below 60 = F

Disabilities Accommodation:

The University of North Texas complies with Section 504 of the 1973 Rehabilitation Act and with the Americans with Disabilities Act of 1990. The University of North Texas provides academic adjustments and auxiliary aids to individuals with disabilities, as defined under the law.
