COURSE SYLLABUS

1. TITLE OF COURSE: Mechanical Design II
PREFIX/NUMBER: ENT 234 CREDIT HOURS: 3.0
2. PREREQUISITE: ENT 233
3. RESOURCES NEEDED:

TEXT:

Machine Design by Robert H. Creamer, 3rd edition Addison Wesley Publishers.
Machinery’s Handbook

SUPPLIES:

Notebook, pencil, 3 ½” HD floppy diskettes and calculator
4. COURSE DESCRIPTION: The layout and design of mechanical systems, tool selection, standard parts selection, report and specification writing, and part ordering techniques will be covered.
5. COURSE GOAL: The student will demonstrate the ability to design and document various types of machine components used in modern manufacturing. The student will also produce a term project, which will consist of a complete machine system design based on a specific machining problem presented by the instructor.
6. COURSE OBJECTIVES:
  A. The student will describe the effects of mechanics and strength of materials on machine component design.
  B. The student will be able to list and describe the effects of friction and lubrication on machine components.
  C. The student will be able to describe the types of bearings used in machine systems and their applications.
  D. The student will describe the factors involved in shaft and seal design.
  E. The student will be able to list various fasteners, couplings, keys, and retaining rings used in machine systems and describe their usage.
  F. The student will be able to identify types of belting used in machine systems, describe their usage, and calculate their lengths.
  G. The student will be able to apply the principles of chain drives, hoists, and conveyors to a machine design.
  H. The student will be able to describe the factors involved in designing braking systems for machinery.
  I. The student will be able to describe the factors involved in designing machine component clutches.
  J. The student will be able to list the various types of power screws used in machinery and their design criteria.
  K. The student will be able to design various types of gears.
  L. The student will be able to describe the factors involved in producing cam designs.
  M. The student will be able to design springs and to select existing standard springs required for specific applications.
7. EVALUATION PROCEDURES:
The student receives a letter grade based upon the successful completion of tests and lab projects assigned by the instructor.  At the completion of this course the student should be familiar with the methods used to produce machine component and system designs to meet specific criteria. This will be evidenced by the completion of course assignments and tests at a minimal 76% or better level.
Each quiz and lab assignment is worth 100 points.

GRADING SCALE

Raw Score Range

 Letter Grade Grade Point Earned
100 to 94 A 12
93 to 87 B 9
86 to 76 C 6
75 to 70 D 3
69 to 0 F 0
The total number of points earned by each student divided by the points possible will give a percentage that relates directly to this grade chart for the final grade.
A final examination of appropriate difficulty and point value will be given which reviews all of the concepts covered in the course.
Special Remarks:
1. Attendance:  College policy states that students may be dropped from enrollment when absent 20% of the scheduled class meetings.  If enrolled from the beginning of the term, 15 hours will usually constitute 20% of a four-credit semester course which meets five hours per week.  Reinstatement procedures are described in the PCC catalog.
2. Tardy Policy:  A student who is late three times (enters classroom after the instructor has taken roll) will be charged with one full absence unless the student can provide valid reasons for one or more of these tardies.
3. Assignments/Missed Exams:  It is the student's responsibility, whether present or absent, to obtain all material presented and to complete all course assignments.  If prior arrangements are made or extenuating circumstances exist, makeup of tests may be allowed.  Late homework papers will not be accepted unless those same extenuating circumstances exist.  Makeup of quizzes is to be at the instructor's discretion.
8. COURSE OUTLINE
9. METHODS OF INSTRUCTION:
To be successful in this course, students are expected to participate in discussions, readings, in-class writing, and peer review activities. The instructor may assign point values to such activities.
10. ACADEMIC INTEGRITY:
The very nature of higher education requires that students adhere to accepted standards of academic integrity. Therefore, Pueblo Community College has adopted a policy of academic conduct as described in the Student Handbook. Violation of academic integrity may be defined to include the following: cheating, plagiarism, falsification and fabrication, abuse of academic materials, complicity in academic dishonesty, and personal misrepresentation. It is the student’s responsibility to be aware of the behaviors that constitute academic dishonesty. Sanctions for violating the standards of academic integrity may include warning, probation, suspension, and/or failure of the course or assignment at the discretion of the instructor.
11. ADA NOTICE:
Students who have a documented disability may be eligible to receive accommodations for this class. Please contact the Disability Resources Center at 549-3446 for further information.
