Your assignment for tonight is twofold.
1) Write a clear purpose for the torque lab. Remember why perform labs ( experiments) in this in general.
2) I hope that many and perhaps most of you now understand a lot more about torque and balancing, so your assignment is to go back and do the problems you couldn't do before. You should be able to do all the problems from the in class worksheet (especially the last one with the off center meter stick), the book stack problems, and most of the book problems. Section 3 (7th period) should all be able to do the piano and beam problem from the book. Section 2 should try it again, and we'll go over it tomorrow.
I'll post the solutions for the in class problems soon
