used in the trial and then measure the reach of the beams and then make a comparison to the mass of the second method is the gravity of the mass that has a fixed size, but change the pivot point of the beams and then save the settings to compare, and the third way is to measure the frequency of the vibration of 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.
The length l constant mass change. The second set to mass m constant change length l to 3 for the frequency change when compared to the length l, 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.
