A shaft has three inertias on it, and they are 15, 30, and 10 kg. m² respectively from left to right. The shaft connecting first two inertias has a stiffness of 4 MN m/radian and the shaft connecting the last has a stiffness of 2MN m/radian. The system is supported in bearings at both ends. The inertias of all shafts can be neglected. Fill in the blank positions of the Holzer table (without using software) and determine the natural frequencies of the system.
