A meter stick of mass 0.44kg rotates in the horizontal plane about a vertical axis passing through the 30cm mark. What is the moment of intertia of the stick? (Treat it as a long uniform rod).
Moment of inertia for a long uniform rod (axis through center): (1/12)ML2
Moment of inertia for a long uniform rod (axis through end): (1/3)ML2
The Attempt at a Solution
LB=0.70m (I'm not sure how to determine the length/axis for LB???)
I=1/3LA2 + 1/3LB2
I=1/3(1.0)2 + 1/3(0.70)2
I= 0.50 m x N
