COURSE OBJECTIVE

The objective of this course is to provide a thorough and systematic introduction to the subject of dynamics of particles and rigid bodies using a Newton-Euler approach. The course provides a rigorous introduction to kinematics of particles and rigid bodies, kinetics of a particle, kinetics of a system of particles, and kinetics of a rigid body. All development is done in a coordinate-free manner and will be applied to examples in a way that provides insight into the structure of the underlying physical process.

COURSE TOPICS

Kinematics or particles and rigid bodies, kinetics or particles, kinetics of a system of particles, kinetics of a rigid body, and principles of work, energy, and momentum.

LECTURE VIDEOS

Below is a set of lecture videos on engineering dynamics. The lecture videos provide the equivalent content of the actual lecture and can be used as supplemental material.

HOMEWORK ASSIGNMENTS

The homework assignments are shown below and consist of three (3) theory assignments and seven (7) problem sets. The three theory homework assignments will each be worth four (4) percent of your grade (for a total of 12% of your total grade). The seven problem sets will be each be worth 1.142 percent for a total of 1.142 x 7 = 8 percent of your grade. For each of the problem solving assignments your grade will be based on the grading of one problem that will be chosen at random. Although the entirety of each problem-solving assignment will not be graded, you are expected to do all of the problems on these assignments them because your performance on the exams will depend upon your ability to solve problems. __All assignments are due at 5:00 PM on the due date and must be submitted to the homework box that will be placed outside of MAE-A 304__.

EXAM SCHEDULE, FORMAT, AND EXPECTATIONS

EXAM FORMAT

All exams will be held in the evenings during periods E2 and E3 with a duration of 1 hour 50 minutes for each exam. It is important to note that in this course you will be examined on a balance of both theory and problem solving. Specifically, each exam will consist of 40 percent theory and 60 percent problem-solving. Because of the manner in which the exams are structured, it is *extremely important* that you understand the theory in addition to just being able to solve problems. Furthermore, because the homework questions take a great deal of time and thought, I urge each of you to do the assignments on the schedule I provide and not wait until the last minute to complete the assignments. If you procrastinate on completing the homework assignments, it will be reflected in your exam and quiz scores.

MATERIALS PERMITTED FOR USE DURING EXAMS

The following list comprises a complete list of the only materials that are permitted for use during the exam:

- A paperback or hard cover copy of the course textbook (electronic versions of the book are not permitted)
- Your own personal handwritten course notes (if you takes notes on a tablet, then you must print these notes)

Other than those materials listed above, no other materials may be used (other than writing implements such as pens, pencils, and erasers). You may not use any electronic aids of any kind including but not limited to laptops, tablet computers (iPad, Microsoft Surface, etc.), cell phones, iPods, or calculators.

ATTENDANCE RULES

Regular attendance is expected of all students. All attendance rules will be follow the official University of Florida Attendance Policies as found by clicking here. Attendance will be monitored via in-class quizzes that will not be announced in advance of the lecture (see grading below).

MAKE-UP EXAM POLICIES

The following list comprises the only legitimate reasons to request an exam make-up or reschedule: (1) a student illness with a note from a physician that the student was ill on the date of the exam; (2) a family emergency that requires immediate attention; (3) a legitimate absence based on the University of Florida approved absences for University related participation in extra-curricular activities; (4) University of Florida exam policies based on a conflict with an exam in another course. In this last case, the exam conflict is resolved in accordance with the rule that the student may ask for the exam in this course to be rescheduled if the other course has a higher course number (that is, a course with number "3402" or higher), but must ask that the exam in the other course be rescheduled if the course number of the other course is less than "3401".

(For Example, Final Grade Reduced from "A-" to "B+")

**100 Percent**

IMPORTANT NOTE: The unannounced in-class quizzes are purely for attendance purposes. As such, these in-class quizzes will not be graded (they are purely self-diagnostic so that each of you can get a sense as to whether or not you understand a particular concept), but missing a quiz on account of an unexcused absence will result in a lowering of a student's final grade in the manner described above (that is, a deduction of one step for each missed quiz on account of an unexcused absence).

GRADING SCALE

Grades in this course are determined using the following scale:

**Letter Grade**

A

A-

B+

B

B-

C+

C

C-

D+

D

D-

E

**Score Range**

1 Standard Deviation Above Course Median and Higher

2/3 to 1 Standard Deviation Above Course Median

1/3 to 2/3 Standard Deviation Above Course Median

0 to 1/3 Standard Deviation Above Course Median

0 to 1/3 Standard Deviation Below Course Median

1/3 to 2/3 Standard Deviation Below Course Median

2/3 to 1 Standard Deviation Below Course Median

1 to 1 1/3 Standard Deviation Below Course Median

1 1/3 to 1 2/3 Standard Deviation Below Course Median

1 2/3 to 2 Standard Deviation Below Course Median

2 to 2 1/3 Standard Deviation Below Course Median

2 1/3 Standard Deviation Below Course Median and Lower

NOTES ON ASSIGNMENT OF FINAL LETTER GRADES

- Given the grading system above, the median grade in the course lies exactly at the boundary between a "B-" and a "B". I reserve the letter grade associated with the median score in the course
*higher*than the boundary between a "B-" and a "B". If the letter grade associated with the median score is increased, then all grades will be increased uniformly by that same amount. For example, if I decide to increase the letter grade associated with the median score in the course from the B-/B boundary (shown above) to the B/B+ boundary, then the letter grades associated with all ranges will be increased by the same amount as the increase in the letter grade associated with the median score in the course. In no case will the letter grade associated with any range be lower than the letter grades shown above. - Scores that lie exactly at a boundary between two adjacent ranges will be awarded the higher grade. For example, a final score of exactly 1/3 standard deviation above the median will be awarded a grade of "B" while a final score of exactly 1/3 standard deviation below the median will be awarded a grade of "B-".
- The grading scale shown above does not include any deductions for missed in-class quizzes ("Course Grading" above).
- Finally, it is noted that while your individual scores for assignments, exams, and quizzes will be posted on E-learning (Canvas), the Canvas portal may not accurately reflect a student's relative standing in the class. Regardless of the information that is seen in Canvas, computation of final grades will be based on the criteria set forth above and a student's grade will only be final when grades have been computed at the end of the semester.
