By using a<br \/>\nmechanical wave driver, available in introductory undergraduate laboratories, we provide various<br \/>\nexperimental results for end loaded cantilever beams that fit reasonably well into a linear<br \/>\nequation. The behaviour of the cantilever beam?s weak-damping resonance response is studied for the<br \/>\ncase of metal resonance strips. As the mass load increases, a more pronounced decrease occurs in the<br \/>\nfundamental frequency of beam vibration. It is important to note that cantilever construction is<br \/>\noften used in architectural design and engineering construction projects but current analysis also<br \/>\npredicts the influence of mass load on the sound generated by musical free reeds with boundary<br \/>\nconditions similar to a cantilever beam.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This article presents several simple experiments based on changing transverse vibration frequencies<br \/>\nin a cantilever beam, when acted on by an external attached mass load at the free end.
