Prerequisites: Phys 170.

Time and location: The class takes place T/Th 8:30 am-10:30 am in Hennings 201. The tutorial is on Friday, same place at 10 AM. Start date: May 14, 2013. End date: June 27, 2013

Midterm: Friday, June 7, 10AM in Hennings 201.

Exam: Friday, June 28, 2013, 10:00 AM am-12:00 noon in Hennings 201.

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 Wednesdays 5:15-6:15 pm (Hennings 338).

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.

## Course outline

• Planar kinematics of rigid bodies. (40%)
• Planar kinetics of rigid bodies. (40%)
