Re: Radius of gyration and moment of inertia (Dallas Warren) Yes of course the ratios are similar. The shapes are similar But when I measure the distance of the two agrregates in VMD , the length of the aggregates and the width of the aggregates are more or less of the same dimensions. Which means that the size of the aggregates are comparable and there is no difference in size. So the Ix Iy Iz values should be comparable in both the aggregate and not 4x times different.I want to know why the the Ix Iy Iz values are 4x times different when the shape dimensions are similar. The aggregate size is similar.
