I've recorded 4 videos for Lecture 6A on Illinois MediaSpace. 
They reside in the PHYS325 channel.

Direct links:
  • Lec 06A-1 - Two More Collective Formulae
	derivation of moment-of-inertia formula
  • Lec 06A-2 - Two More Collective Formulae
	derivation of Parallel Axis Theorem
  • Lec 06A-3 - Rolling Without Slipping
	derivation of the no-slip rolling condition
  • Lec 06A-4 - Example & Contact Point Technique
	use of contact point as torque-law reference in rolling problems

Please do your very best to view these videos before Lecture 7A. 
I am sorry for the delay in getting them posted, it was a rough trip last week.
The essential segments for this week's homework are 06A-3 and 06A-4,
but they are all important.
  • I've also place screenshots (usual "blackboard" format) in Blackboards
  • Please bring your questions to class, I'm sure you have great ones! :-)

Cheers, everyone, and thank you for your patience!
