This is a study of the mechanics of particles and rigid bodies. Topics covered include: kinematics and kinetics of particles; work and kinetic energy; impulse and momentum; rigid body motions; relative motion; and moving coordinate systems.
For the student who wishes an overview of the subject, the topic coverage is broad enough to provide a comprehensive introduction.
The text for the course is
Engineering Mechanics: Dynamics, Latest edition or earlier, Hibbeler, Prentice Hall, or Statics & Dynamics package.
If you have the older versions, you can still use them, but remember to check the problems at the end of each chapter, for doing your homework assignments, as these are changed in the new edition.
The text is meant as a reference and for supplemental assigned reading, lecture notes will deviate in both content and approach.
Other suggested textbooks are:
- Engineering Mechanics: Dynamics, by W.F. Riley and L.D. Sturges. Published by John Wiley and Sons, Inc., New York.
- Engineering Mechanics: Dynamics & Dynamics Study Pack, by A. M. Bedford and W. Fowler.
- Engineering Mechanics: Dynamics (Engineering Mechanics) by J. L. Meriam and L. G. Kraige.
- Vector Mechanics for Engineers: Dynamics by F. P. Beer, Jr., E. R. Johnston, W. E. Clausen, and P. J. Cornwell.
Your grade in this course will be determined from your performance on homework assignments, quizzes, mid-term and final examinations.
- Homework 10%
- Mini-tests 40%
- Midterm Exam 25%
- Final Exam 25%
[90 - 100% = A, 80 - 89% = B 70 - 79% = C 60 - 69% = D Below 60% = F]
Homework assignments will be assigned after certain modules have been completed. The format for the tests and final examination will be proctored and will be announced well before each test.

Take-home Tests:
Solve the following problems (but do not hand them to me!). These take home tests have no due dates, they are prepared for you to make you ready for the tests.
First try not to look at the solutions. Time yourself and then check if you have answered the problems correctly.

Homework:
- Problems are due the week after they are assigned.
- Problems will be graded only if they are written neatly.
- Cooperation on understanding and doing the homework is allowed, but the final presentation must be your own (no copying of homework).
- No late homework! There will be no extension for the due date.
- For group homework, each group brings just one homework, but all group members should learn how to solve the problems, because you are asked to come and solve it in the class. If you fail to explain the problem well, the whole group members lose few marks, and you will lose the whole mark.
- Follow the rules for presenting problem solutions written in the following section (Tests, Final Exam).

(*) Choose a partner for yourself and solve the problems together. Submit one assignment per group. Allocate the time that each of you two spend on the assignments and sign it. If you spend the same amount of time, you can mention it as well (I need to see your names and signatures on the first page when you submit your assignments). You can work alone, if you wish, but remember that working in a group has a higher efficiency.
(**) Each problem should not take more than 15 minutes. Train yourself to think and write faster!
(***) Try to work on yourself and be stress-free during your test. Review the lecture notes online and solve the study pack problems.
RULES FOR PRESENTING PROBLEM SOLUTIONS.
- Neat and appropriate diagrams are required (eg a “Free Body Diagram,” or sketches showing the forces, dimensions, angles, etc).
- First write equation in general form (such as ΣF = ma) and then substitute the forces. If a variable represents a vector, the arrow must be included.
- When numbers are substituted into equations, include basic units and powers of ten. Correct units should accompany all numbers.
- Never calculate a value and then enter it into an equation that is higher up on the page. The person who is checking your work needs to see the sequence of the calculations.
- Initial or intermediate calculations must be done more precisely (usually 4 or 5 significant digits) than the answer will show.
- Express answers in Engineering Notation, to 3 significant figures (usually), with correct, convenient units.
- Either show the angles or calculate the appropriate ones, considering the positive x axis as the starting point and rotating CCW.
