cheers everyone =] especially rohanprbhu :D

i think r is the distance from the original point to the centre so l/2

Oh thank you i think its cos i forgot the 6 as the denominator =/ parallel axis theorem is I=I(centre of mass)+Mr^2 I think so taking that I you get Ml^2/3=I(cm)+Mr^2 I(cm)=Ml^2/3-Mr^2

So I get lim n-->infinity = 3l^2

I don't think I can use calculus on this problem because we haven't learned it yet. I only know difrrentiation, not much integration =/. On the m, forgot that XD Is it possible to use mathematical induction to solve the infinite series if i use n lengths?

Homework Statement 1a . By dividing a uniform narrow bar of length l into a number of small masses, find the moment of inertia of the bar rotating about an axis perpendicular to the bar and passing through its end 1b. use the parallel axis theorem and the result above to find the moment...
