The experiment Vibration Method: Vibration of Cantilever is an experiment order to find Young’s modulus of the ruler that is supposed to be the Long Bar ,which the trial from two methods.
The first method is set to the length of the rotation of the beams, fixed, and then make the change the mass
and set to the mass, fixed, and then make the change the the length of the rotation of the beams. second method is way the frequency change when compared to the length of the beams.
Overall this experiment result fond the Young’s modulus of first method ได้
〖 γ〗_1=19.891±0.653 GPa,〖 γ〗_2=19.762±0.864 GPa and fond the Young’s modulus of second method is 〖 γ〗_3=18.734 GPa and error from the standard of first method is 1.23% ,0.57% second method is 4.66 % .
