**Exam:** Friday, June 26, 2015, **10:00 AM am-12:00 noon** in Hennings 201 (tutorial slot).

**Credits:** 2.

**Grading:** 25% test exams (work/ group work in the tutorials), 15% Mastering Engineering homework assignments, 20% midterm, 40% final exam.

**Office hour:** My office hour is Tuesdays 5-6 pm (Hennings 338) [adjustable].

**Book: ** Engineering Mechanics, Statics and Dynamics, by R.C. Hibbeler (UBC custom edition is recommended, but any edition will work).

**`Mastering Engineering' software:** In addition to Hibbeler's book, you will need *Mastering Engineering*, a web-based software that will be used for homework assignments. Mastering Engineering can be purchased either in a package with Hibbeler's book or separately.

**Lecture Notes:**

- Planar kinematics of rigid bodies. (40%)
- Planar kinetics of rigid bodies. (40%)
- Conservation laws etc. (20%)

We cover chapters 16 to 18 of Hibbeler's book.
