Homework, quiz, & exam policies

Homework & homework quiz policies

Weekly homework will be “due” on Fridays, but it will not be turned in for credit. However — and this is very important — each week a quiz will be given that will cover that week’s homework.

Quizzes will be available on moodle each week (as early as I can get them up), and must be completed by Sunday (before midnight). Late quizzes will receive no credit. Multiple attempts may be made on the quizzes (you will receive your mean grade).

Working in groups on homework is strongly encouraged, but quizzes must be completed individually.

Exam policies

The midterm and final exams will be in-class. If you require any specific accommodations, please contact me.

Calculators will be allowed. Only ones own notes and the notes provided by the instructor will be allowed. No communication-devices will be allowed.

No exam may be taken early. Makeup exams require a doctor’s note excusing the absence during the exam.

The final exam will be cumulative.

Grading policies

Total grades in the course may be curved, but individual homework quizzes and exams will not be. They will be available on moodle throughout the semester.

Homework quizzes: 25%
Midterm Exam: 35%
Final Exam: 40%

Academic integrity policy

Cheating or plagiarism of any kind is not tolerated and will result in a failing grade (“F”) in the course. I take this very seriously. Engineering is an academic and professional discipline that requires integrity. I expect students to consider their integrity of conduct to be their highest consideration with regard to the course material.

Correlation of course & program outcomes

In keeping with the standards of the Department of Mechanical Engineering, each course is evaluated in terms of its desired outcomes and how these support the desired program outcomes. The following sections document the evaluation of this course.

Desired course outcomes

Upon completion of the course, the following course outcomes are desired:

students will understand the design process;
students will have experience working in teams on design problems;
students will understand stress and strength analysis;
students will understand material properties;
students will understand static and dynamic loading failures;
students will understand how to design with shafts and shaft components;
students will understand how to design with screws, fasteners, and other nonpermanent joints;

students will understand how to design with mechanical springs;
students will understand how to design with shafts and shaft components;
students will understand how to design with bearings; and
students will understand how to design with gears.

Desired program outcomes

The desired program outcomes are that mechanical engineering graduates have:

an ability to apply knowledge of mathematics, science, and engineering;
an ability to design and conduct experiments, as well as to analyze and interpret data;
an ability to design a system, component, or process to meet desired needs;
an ability to function on multi-disciplinary teams;
an ability to identify, formulate, and solve engineering problems;
an understanding of professional and ethical responsibility;
an ability to communicate effectively;
the broad education necessary to understanding the impact of engineering solutions in a global and social context;
a recognition of the need for, and an ability to engage in life-long learning;
a knowledge of contemporary issues; and
