CATALOG DESCRIPTION
MENG 375 Machine Elements I
Systematic approach to design; standardization, dimensioning and tolerancing; strength
of mechanical elements; theories of failure under static and dynamic loading situations;
impact loading; shaft design: screw threads and threaded fasteners; power screws;
bolted and riveted joints in shear; keys and couplings. (Prerequisite: MENG 222
Strength of Materials)
Required Background:
It is expected that the student taking this course have a good background and problem
solving skills in: Statics, strength of materials, calculus, and trigonometry. Also
knowledge of dynamics, materials, and manufacturing processes would be helpful.

Course Objectives:
1. To develop an understanding on the fundamentals of the mechanical design
process,
2. To develop good and careful problem formulation and solution skills for
designing selected machine components and systems.
3. To develop an ability to make proper analysis and assumptions by employing
the concepts and theories.
4. To develop an understanding of standards, tolerances and fits.
5. To develop a working knowledge in the use of various standard procedures and
catalog information in the identification and selection of engineering materials.
6. To develop an understanding of the importance of safety, reliability, and cost
factors in design.
7. To develop an ability to work well as a part of a team.
Course Outcomes:
The student, after satisfactorily completing this course, will be able to:
1. Apply the design process to engineering problems, including the consideration
of different technical alternatives while bearing in mind cost, environmental
concerns, safety, and other constraints.
2. Use material properties data for strength, stiffness, and ductility in the analysis
and design of machine elements to insure safe operation.
3. Identify loading of machine elements and perform stress and deformation
calculations to design safe machine parts.
4. Design machine members subjected to axial tensile and compressive forces,
bending moments, and torsion.
5. Design long and intermediate length columns.
6. Properly consider loading, stress concentrations, and fatigue in design
calculations.
7. Analyze combined stresses using Mohr's circle.
8. Get familiar with codes and standards in relation to machine elements.
9. Select and specify materials, and understand the importance of tolerances and
fits in critical design applications.
10. Appreciate the importance of working in teams.
