Abstract
The purpose of this experiment was to determine the relationship between weight and vibration on the drive shaft of a helicopter. This can be useful in fields that specialize in helicopter maintenance, such as mechanical engineering or mecatronics. The procedure for the experiment was as follows. First, different weights were placed on a scale, and then applied on a helicopter drive shaft. The driveshaft was then spun at a high speed and the vibration was recorded in ips. Finally, the data was recorded on a graph to determine the relationship. The result of the ips of an single factor ANOVA test of the data had an F value that was higher than the F critical, meaning the data supported the hypothesis. The weight and vibration have no correlation. In conclusion, the data suggests that vibration is not affected by weight. This could have been due to mismeasuring the weights or perhaps the weight did not have a great enough effect to affect the vibration. The information gathered from this experiment can be used in other fields that pertain to helicopter maintenance.
