DO NOT OPERATE THE BEAM AT 9 Hz. – excessive vibration will occur! B. Measure Damping and Natural Frequency. Pluck the beam to get LVDT amplitude as a function of time. (Set 512 Hz. & 1024 samples – SCOPE; Pluck the beam, wait about 1 second and then hit “enter”.) Measure the damped natural frequency averaged over several cycles.

The mass of the structure is 5000 kg and is concentrated on the beam that is assumed to be rigid. The two columns are assumed to be mass-less and each has a flexural stiffness (EI) of 4.5x106 Nm2. If the structure has a damping ratio (ζ) of 4% (=0.04), calculate; (a) the undamped natural frequency and (b) the damped natural frequency.

This frequency where the inductive and capacitive impedances cancel is called the resonant frequency. You will recall from Experiment 3, that oscillating systems usually have such a natural resonance. Driving the cantilever beam at its natural resonant frequency caused it to undergo the largest oscillations.

Natural frequency: frequency of free vibrations of the system. Description of the apparatus: (Refer fig.). The apparatus consists of a central column supported on a base. A collet is provided at the top of the column through which a spring is attached. A cylindrical mass carrying a stylus is attached at the lower end of the spring.

Note that beam theory does not give an exact solution to the cantilever beam problem. It is a clever approximate solution, which is valid only for long slender beams. We will check to see where beam theory starts to break down next. Repeat the FEM calculation for …
