Seven IRE students traveled to Mankato University last week to take part in a vibrations lab. We were able to complete seven labs that dealt with various topics in vibrations, ranging from torsional systems to vibrations of an airplane wing.

The labs were successful, giving us hands on experience in areas that we have been studying theoretically.
Shown below are two of the systems that we worked on. The first was a rotational system that was out of balanced. We were required to add weights to different areas to balance the system. The second system had a forced vibration and a vibration absorber. We were able to make the center of the system almost completely still by driving it at the natural frequency of the absorber.
