Final Examination…Tuesday, Dec. 16, 12:30-2:30 PM, ME 218

 

   Engineering Mechanics is an accelerated course for students who want a basic foundation in engineering mechanics with fewer mechanical and civil engineering applications than found in more conventional courses. The course will provide adequate background for students who wish to go on to study vibrations or advanced topics in applied mechanics. Since the material covered in this course will be condensed from a textbook that is designed for more general course, it will be especially important for students to attend class lectures regularly.

 

   Class sessions will emphasize fundamental concepts, and two homework assignments will be assigned each week. Homework will help students learn to apply the ideas discussed in class and will generally be due at the beginning of the next period. Like all engineering or science courses, there is no possibility developing proficiency with the material or passing the course unless the student works a substantial majority of the homework.

 

Course Objectives:

∙ To build on basic fundamentals and expand students’ understanding of mechanics learned in physics.

∙ To develop students’ problem-solving capability.

∙ To develop students’ ability to analyze mechanical/physical problems.

∙ To develop vocabulary to enable students to interact with other engineers.

∙ To provide a foundation for further study in controls and vibrations of physical systems.

∙ To cultivate an appreciation of technical subjects that are not in the students’ major.

 

Course Outcomes:

∙ An understanding of basic scientific principles, including calculus, differential equations, mechanics, properties of matter, and related topics.

∙ An ability to approach and solve engineering problems in a structured manner.

∙ A sensitivity to an practice of personal and professional ethics.

 

The final grade for the course will be determined from the results of the homework, hour examinations, final exam, and classroom participation, using the following weights:

 

   Homework                                                                           35%

   Midterm Exams (3-4)                                                           35%

   Final Exam                                                                           20%

   Classroom Participation and Other Involvement                 10%
