What does the mass and spring represent in explaining a mass = inertia
vibration? spring = elasticity
Sinusoidal vibration equation
cycle one complete oscillation of vibration
time to complete one cycle
Pr = 1/f in sec
period
Pr = 1000/f in msec
ex: Pr = 1/4hz = .25 sec
the number of complete wavelengths (cycles) that pass a
point in a given time
frequency f = 1/Pr in sec
f = 1000/Pr in msec
ex: f = 1/.25 = 4hz
total distance from point of positive maximum displace-
ment to negative maximum displacement
peak to peak amplitude
maximum distance moved
peak amplitude
the square root of the mean of the squared deviations of
the instantaneous values
root mean square amplitude
steps:
1. each amplitude of a waveform is squared

starting position of a vibration relative to a reference start-
starting phase ing position, a complete sinusoid cycle corresponds to one
circular turn
0 degree starting phase (or 360)
90 degree starting phase
180 degree starting phase
270 degree starting phase
air density how closely packed the air molecules are
Brownian Motion The continuous random motion of small particles
-pressure created by air molecules that is proportional to
the density of molecules
static pressure
-changes in pressure are due to vibration are changes in
static pressure
# of molecules per unit area
density - D = # + area
-density of air varies per moisture, altitude, and pollution
