Torque and Equilibrium

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

Net force = 0
Net torque = 0

We did a problem together and Rotational 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 19th. You will have the next class period to work on this, but no other class time.
