Hi, everyone. I'm required to complete an open ended analysis of the following problem:


I'm not requesting a solution, I'm only looking for assistance in relation to determining the spring stiffness and natural frequencies of the rigid body.

Please explain your understanding of the extract highlighted in the above image. Hence, what is significant about the forcing frequency being greater than the second rigid mode frequency? And how does this assist with determining the spring stiffness or natural frequency of the lumped model.

Please note this is a second degree freedom system, with a linear (up-down) displacement and an angular (about the center of mass) displacement.

Thanks in advance!
