Textbook:   Engineering Mechanics: Dynamics, R.C. Hibbeler, Fourteenth edition,  Pearson © 2016

Note:  Older editions and International edition will also work for lecture material. However, homework problems are assigned from 14th 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 12     Kinematics of a Particle            
Chapter 13     Kinetics of a Particle:  Force and Acceleration  - Except section 13.7
Chapter 14     Kinetics of a Particle:  Work and Energy  
Chapter 15     Kinetics of a Particle:  Impulse and Momentum  - Except section 15.9
Chapter 16     Planar Kinematics of a Rigid Body
Chapter 17     Planar Kinetics of a Rigid Body: Force and Acceleration
Chapter 18     Planar Kinetics of a Rigid Body: Work and Energy

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

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


Approximate midterm dates:  Midterm 1 (Thursday April 26)                  Midterm 2 (Tuesday May 22)

* 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 one 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 indicated date and time. Late HW will not be accepted.  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 credit on that homework set.

Homework Submission guidelines:

1)      Entire 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:
