Rotational Force or Torque
DoNow: Two kids are using a 10.0 m long see-saw to learn some physics. One has a mass of 40.0 kg, while the other has a mass of 50.0 kg. What happens? Can the less massive kid ever come down? Can see-saw ever become balanced? (notes)
AIM: I can describe the effect of a force or multiple forces on the rotation of an object.

Wow, What Goes Around #3 is challenging!
AW in 3rd period mentioned an error I made for the moment of inertia. There is not really a constant for MR^2 since the M's and R's are different. The best I could do was solve for I = {[(M1)/4]+[(M2)/6]}L^2 or {(M1)+[2/3(M2)]}R^2.
As a result, I changed the worksheet.
Enjoy!
