Objective: (3 sentences)
The goal of this experiment is to study the vibrational characteristics of a cantilever beam subjected to dynamic excitation. Students will use a shaker to excite the beam and a laser system to monitor its displacement, allowing them to analyze the beam's response at various frequencies. This will include identifying resonance frequencies, mode shapes, and understanding how the beam behaves under vibrational forces.
