Torque and Equillibrium

Today we talked about the conditions necessary for equilibrium. That is:

Net force = 0
Net torque = 0

We did a problem together and Rotational Motion TIPERs #4.

Homework is Ch.8 (p. 265) #8 & 21

We also passed out the instructions for our Mobile Project, which will be due on January 25th. You will have the modular day on January 23rd or 24th to work on this in class, but that's it. I am hoping most people will only be finishing off their mobiles on that work day and will be able to turn it in right then.
