Textbook:   Engineering Mechanics: Dynamics, Meriam and Kraige, Eighth edition,  John-Wiley and Sons,  ISBN: 978-1-118-88584-0, ©2015

Note:  Older editions and International edition will also work for lecture material. However, homework problems are assigned from the eighth ed. and students are responsible for obtaining and solving correct problems.

Course Objectives:

1) Extend the previous knowledge of physics (mechanics) to particle motion kinematics, including projectile motion.
2) Solve particle dynamics problems using Newton's Second Law and concept of Free Body Diagram.
3) Apply Work-Energy Principles to the particle dynamics problems.
4) Apply Impulse-Momentum Principles to the particle dynamics problems.
5) Understand the motion of rigid bodies, concept of moment of inertia.
6) Understand the concept of relative velocities and acceleration in rigid bodies, including relative motion of coincident rotating bodies and Coriolis Acceleration.
7) Solve kinematics problems using vector cross product concepts and unit vectors.
8) Apply concepts in objective 2-4 to the rigid body Kinetics.

Textbook Topics:

Chapter 1     Introduction to Dynamics            
Chapter 2     Kinematics of a Particle - Except section 2/7            
Chapter 3     Kinetics of a Particle:   - Except sections 3/13 and 3/14
Chapter 4     Kinetics of Systems of  Particles- Except section 4/7
Chapter 5     Plane Kinematics of Rigid Bodies
Chapter 6     Plane Kinetics of Rigid Bodies 

Grading Policy:  Grades will be based on homework assignments and exams as follows:

Homework assignments 10%
Two midterm exams * 55%
Final exam (comprehensive) 35%


Midterm exam schedule:   Midterm 1 (Monday April 25)                  Midterm 2 (Monday May 16)

* No make up exams will be given. Percentage of missed exam will be added to the Final exam percentage.

Note to DRC students: If you are approved by the DRC for test accommodations it is your responsibility to schedule the exam with Testing Services.  Your exam cannot start earlier than 1 hour before or later than one hour after the scheduled exam time.  Notify me before each exam when your exam will start so that I can have an exam at the Testing Center.  Schedule your testing times at the very beginning of the term to ensure you can get a test time that meets the start requirements.  I will not offer a special proctored exam.

Homework Assignments and Due dates:    Homework is due at the beginning of the class (Maximum of 5 minutes after the official start time of the class).  Late homework will not be graded. Submit HW electronically as pdf file to the course section of D2L. Students who present the homework solution using Mathcad will receive a 10% bonus point on that homework set.

Homework Submission guidelines:

1)      Each homework set must be submitted as one (single) PDF file.

2)      Only PDF format will be accepted and graded. Other formats (including JPEG images) will be ignored and will not be graded.

3)      Use the following naming convention for homework:

 Last-name_First-name_hwxx   (where xx indicates the set number).    For example: Smith_Jane_hw2.PDF

4) If you revise your submission send a message from D2L alerting the grader about the changes.

Classroom attendance and etiquette:

Attendance IS NOT mandatory. However, if you attend the class you are required to observe the following guidelines:
