A generic expression of the inertia equation is I = k m r2(2c) where k = inertial constant - depending on the shape of the body Radius of Gyration (in Mechanics) The Radius of Gyration is the distance from the rotation axis where a concentrated point mass equals the Moment of Inertia ...
The band gap width of the zigzag beam-supported stepped PnCs is higher than the straight one due to the change of the mass inertia moment. The zigzag beam in the PnCs based on analysis of the mass inertia moment revealed the increase of the first band gap by 17.25kHz, which is 60% ...

The values of m1 and m2 can be determined using the conditions that: (i) the total mass must be the same for both systems; (ii) the center of mass must be the same for both systems; and (iii) the moment of inertia must be the same for both systems, which yield the relations: ...
