Grading: Homework 9%, Bucks 8%, Quizzes 4*12%-48%, Final 35%.

Homework format: Use 8.5x11-inch paper. Write only on one side. Start each problem on a new page.

Note: Homework counts 9% if it is done and handed in on time. No late homework is accepted. It is unacceptable not to do homework and will count severely against you if it is not completed and turned in.

Special Note on Class and Homework Preparation:

Learning any topic in Mechanical Engineering is a partnership between the professor and student. The amount learned and the degree of retention depends primarily on your involvement in the subject matter. You should be aware already that if your level of effort in a course is low, you are not likely to learn much. To maximize your absorption and retention of material, I require that you read the above class assignments and attempt to do the assigned homework prior to coming to class for that day. Homework assigned for a particular class will be collected at the first of the class period following that for which it is assigned. Occasionally I may check your homework the day it is assigned to make sure that you are attempting to do the homework prior to class. It is your responsibility to make a good attempt at doing your homework prior to the class for which it is assigned.

It is good for you to stay prepared for class, to come to class having read what material is to be covered in the class. When reading the material, if you encounter points that you do not understand, make a note of them--better yet, formulate a question conserning them--and bring that to class in order to pose questions about the points you do not understand. Homework is assigned for each reading assignment. Homework problems are turned in once a week, on Friday. All problems assigned prior to that Friday are due to be turned in that Friday. So, for example, you would turn in the homework sets for lessons 8-10 on Friday, 27 January. Do not wait until the night before they're due to undertake the homework problems for the previous week. Work homework problems for a class prior to coming to class that day for that topic. You may not be able to finish the entire homework set prior to a class, but having made the attempt before coming to class will help you understand the material for that lesson during class.

Course Learning Outcomes:

Students understand displacement, velocity, and acceleration in both scalar and vector terms for rectilinear and curvilinear motion.
Students can apply the above concepts to analyze the motion of particles undergoing variable acceleration.
Students understand Newton's laws of motion and can apply them to typical engineering problems of particle kinematics.
Students can analyze 2-D rigid-body motion with both absolute- and relative-motion descriptions.
Students understand the equations of motion for rigid bodies in plane motion.
Students can identify and use the work/energy and the impulse/momentum priciples in plane-motion problems.
Students can effectively communicate legible problem solutions to be understood by engineers in and out of their specific discipline.
