A typical sinusoidal vibration test profile is shown in Figure 2. The amplitude is defined over a range of frequencies. The amplitude can be constant or variable. During a sine vibration test, the vibration wave forms are swept through a range of frequencies, however they are of discrete amplitude, frequency and phase at any instant in time.

Therefore, the shaft can be analyzed as vibrating in the Y direction with a time varying force in the Y direction. The magnitude of the Y force versus time = mass*r*RPM^2*sine(RPM*time), and this is what creates the vibration in the Y direction.
