Unformatted text preview: Physics 114A - Mechanics Lecture 26 (Walker: Ch. 11.1-4) Torque & Equilibrium February 25, 2011 John G. Cramer Professor Emeritus, Department of Physics B451 PAB [email protected] Announcements Homework #8 is due at 11:59 PM on Thursday, March 3. We will have Exam 3 covering Walker, Chapters 9-11 one week from today on March 4. The format will be similar to Exams 1 and 2. There will be assigned seating with new seats, and previous seat requests will be used. My office hours are 12:30-1:20 PM on Tuesdays and Thursdays, both in the “114” area of the Physics Study Center on the Mezzanine floor of PAB A (this building).
