set to the length of the rotation of the beams, fixed, and then make the change the mass 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 trial will be a spring force that not much action to stretch out a little. Estimated to be in a condition known as flat spring and measuring the stretch of the spring. And measuring the oscillation frequency of the spring
