BISOPE series 63- Graphs related to amplitude and frequency       ---------------------------------------------------------------------------

There is an object that changes its position and repeatedly moves back and forth around a certain standard. On the other hand, there are objects that end with a single push or pull. Which one takes more strength? If you look closely at the fitness equipment nearby in your daily life, you will see that what you moved with effort must be returned to its original position before you can apply force in the same direction in the next exercise. In fact, which force is applied is not that important when comparing two movements. However, the key is how much greater force is applied and how often. We understand that all physical waves appear as noise in the air and as vibration (repetition) in objects. And if you draw it as a two-dimensional graph, it can be expressed directly as the X and Y axes. This is ‘change in size over time’.

 

X and Y axes of vibration

 

The X~~~

 

Y axis	Main unit	Displacement (µm, mm), velocity (mm/s, cm/s), acceleration (m/s², G)
	Sub unit	0-peak, peak to peak, rms

 

The ‘Z’ axis (third axis) can be used to express the amplitude of vibration, and it mainly plays the role of RPM in Campbell, Waterfall, etc.
