Forced To Marry (Religious Marriage Documentary) - Real Stories

The result of resonance is always a large vibration. Regardless of the vibrating system, if resonance occurs, a large vibration results. This is often demonstrated in a Physics class with an odd-looking mechanical system resembling an inverted pendulum.

The apparatus consists of three sets of two identical plastic bobs mounted on a very elastic metal pole, which are in turn mounted to a metal bar. Each metal pole and attached bob has a different length, thus giving it forced different natural tube of vibration.

The bobs are often color-coded to distinguish between them; they are colored red, blue and green a set of three colors that real be significant later in The Physics Classroom Tutorial.

The red bobs are mounted on the longer poles and they have the lowest natural frequency of vibration. The blue bobs are mounted on the shorter poles and have the highest natural frequency of vibration.

Note the length-wavelength-frequency relationship that was discussed earlier. When the red bob is disturbed, it begins vibrating at its natural frequency. This in turn forces the attached bar to vibrate at the same frequency; and this forces the other attached red bob into vibrating at the same natural frequency.

This is resonance - one bob vibrating at a given frequency forcing a second object with the same natural frequency into vibrational motion. While the green and the tube bobs were disturbed by the vibrations transmitted through the metal bar, only the red bob forced resonate. This is because the frequency of the first red bob is tuned forced the frequency of the second red bob; they share the same natural frequency.

real forced tube playing with boobs Musical instruments and other objects are set into vibration at their natural frequency when a person hits, strikes, strums, plucks or somehow disturbs the object. For instance, a guitar forced is strummed or plucked; a piano string is hit with a hammer when a pedal is played; and the tines of a tuning fork are hit with a rubber mallet. Whatever the case, a person or thing puts energy into the instrument by direct contact with it. This input of energy disturbs the particles and forces the object into vibrational motion - at its natural frequency. If you were to real a guitar string and stretch it to a given length and a given tightness and have tube friend pluck it, you would hear a noise; but the noise would not even be close in comparison to the loudness produced by an acoustic guitar. On the other hand, if the string is attached to the sound box of the guitar, the naked gingers fucked hard string is capable of forcing the sound box into vibrating at that same natural frequency. The sound box in turn forces air particles inside the box into vibrational motion at the same natural frequency as the string.
