and the third way the frequency change when compared to the length of the beams
without hanging from the mass results from the trial. The first method is the value to the modulus of the ruler is (1.92 ± 0.06) × 1011 pa tolerance from the standard value 6.67% and how the two values to the modulus of the ruler is equal to 2.06 ± 0.06) × 1011 pa tolerance standard value 14.44% and how the three values to the modulus of the ruler is equal to 0.75 ± 0.0.34) × 1011 pa tolerance from the standard value 58.3% which may occur from the point of rotation of the staves change and may be the result of other factors in the trial that cannot be controlled.
l to 3 for the frequency change when compared to the length of the rotation of the beams, then take the data from the trial were three cases to calculate the Young's Modulus of the equation. then the value is compared with the Young's Modulus standards.
