R^3 (lambda) d(theta)?
 one year ago

El_Psy_Congroo!!Best ResponseYou've already chosen the best response.0
correct ... the shape of ring goes all the way round to 360 and varies with d(theta) ... so what do we do?

whole ring? length = r theta I = r^3 theta (lambda)
 one year ago

El_Psy_Congroo!!Best ResponseYou've already chosen the best response.0
no ... this varies with theta ... so we integrate it along 0 to 2 Pi

so what is the final answer?

El_Psy_Congroo!!Best ResponseYou've already chosen the best response.0
yep .. what would (lamda) (2 pi) R = ??

RolyPolyBest ResponseYou've already chosen the best response.0
Wait.. I was partly right.. length = r theta I = r^3 theta (lambda) One more condition there is theta = 2 pi I = r^3 (2pi) lambda

yeah the moment of Inertia of ring is MR^2

Wait, surface / unit area? What's that?
 one year ago

El_Psy_Congroo!!Best ResponseYou've already chosen the best response.0
sorry ... mass per unit area ... typo.
 one year ago

RolyPolyBest ResponseYou've already chosen the best response.0
Mass = sigma (area) = sigma (pi)[(r_2)^2(r_1)^2) = sigma (pi) (dr) (2r+dr) Have to go now. I'm sorry!
