Hey Greg,
the main system is a cantilevered beam with a lumped mass at the end. The beam itself does not have mass. The lumped mass experiences a periodic force excitation. The system can be expressed like follows:
For the SDOF system, the amplification function looks like this:
This is why...
Hello everyone,
I have a simple question. Lets say a single degree of freedom system (SDOF) which consists of a spring and a mass is excited by an external force. The SDOF system has the eigenfrequency of 0.31 Hz and the external force is a periodic force with the frequency of 0.6 Hz. After...
