Today, we'll talk about two problems in the textbook: Ch 12 #38 and #71.  You'll learn how to determine if an object will tip.  For tipping problems, you need to really THINK about the situation as you're drawing your free body diagram.  You also need to think about the best choice of fulcrum.  Finally, using line of action usually helps. 
Homework:  If you haven't finished these problems Ch 12 #38 and #71, you should finish them for homework.    Catch up on any videos you did not watch last week.  If you haven't taken calculus yet, really try to make sense of the time derivative and integral stuff in previous videos.  Watch the following video on how to solve kinematics problems with calculus.  Everyone should at least browse this video so we make sure we're all on the same page.  Clarification:  Make sure your function is a continuous function before you try to integrate.
