Course Goals for the Students:

· Develop an understanding of the fundamental principles of applied kinematics for particles and rigid bodies in engineering dynamics.

· Demonstrate an integrated understanding of engineering dynamics principles through applications involving problem solving and through creation of design solutions to engineering scenarios.

· Work cooperatively to facilitate a collegial atmosphere conducive to learning for all students in the class.

· Prepare for and attend each class by reading the assigned sections before class and participating in class discussions.

Course Goals for the Instructor:

· To provide all students the tools necessary to succeed in their pursuit of a deeper understanding of the principles of applied kinematics for particles and rigid bodies in engineering dynamics.

· To provide all students with an atmosphere conducive to learning the principles of engineering dynamics.

· To provide sufficient feedback to students, enabling them to gauge their progress towards achieving their goal in acquiring a mastery of the principles of engineering dynamics.

· To facilitate student learning through the use of appropriate technology and the illustration of dynamics applications in the real world.

Homework: 3-6 problems will be assigned each class period. All problems assigned during the week will be due the following Tuesday at the beginning of class. The instructor will grade two problems from each assignment (at 5pts each for a total of 10pts per assignment) for prompt return to students. Solutions to all problems will be posted upon return of the homework. The lowest 3 homework assignment scores will be dropped. Late homework will not be accepted after that assignment has been returned to the class. Late homework that can be accepted will have its grade reduced by 50%.

Exams: There will two mid-term exams and a final exam. Each mid-term exam will be worth 100 points. The mid-term exams will be written for 1 hour, but you may use the full 1 hour and 15 minute class period if needed. The final exam will be worth 150 points. The final will be a comprehensive exam with approximately two-thirds of the material coming from topics taught since the last exam, and one-third of the material coming from topics taught before the last exam. No make-up exams will be given. If you have a serious conflict with an exam time, you must discuss it with the instructor and take the exam early. Exams missed due to a serious illness or a family emergency (these must be documented) will be dealt with on a case by case basis.

Group Design Project: The class will be divided into teams of 3-4 members. Each team will produce a design during the course of the semester that involves the use of a number of engineering dynamics principles. Three progress reports worth 15 points each, one final report worth 40 points, and an oral presentation worth 15 points will be graded. This gives a total of 100 points for the group design project.
