 Quote by newcool Consider this problem: http://www.physics.harvard.edu/probweek/prob35.pdf The solution is here: http://www.physics.harvard.edu/probweek/sol35.pdf Why is N and $$mg *\cos\theta$$both positive? I thought N point away from the hoop
No N is inward. The beads try to go outward, but the loop pulls them inward.
 P: 42 Thanks, I got the first part, anyone have any idea bout the second?
