ResonanceWe hear the word “ resonance” used a lot in physics, but let us take a second to ask “What is Resonance?” In order to explain the word, we first need to be thorough with the following terms:. Period – The amount of time it takes to complete one cycle. Frequency – The number of cycles in one second is the frequency of oscillation.Now that we have briefed you with the Period and Frequency, let us understand resonance in the next section. What is Resonance?Resonance occurs when a material oscillates at a high amplitude at a specific frequency. We call this frequency resonant frequency. The dictionary defines resonance as,“the state of a system in which an abnormally large vibration is produced in response to an external stimulus, occurring when the frequency of the stimulus is the same, or nearly the same, as the natural vibration frequency of the system.”Physics defines Resonance asA phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation.

Some Examples of ResonanceBelow we have listed examples of resonance that we can witness in our daily lives:. Musical InstrumentsThe best examples of resonance can be observed in various musical instruments around us.

Whenever any person hits, strikes, strums, drums or tweaks any musical instrument, the instrument is set into oscillation or vibration at the natural frequency of vibration of the instrument. A unique standing wave pattern defines each frequency of vibration as a specific instrument.

Resonance: noun the quality or state of being resonant. A vibration of large amplitude in a mechanical or electrical system caused by a relatively small periodic stimulus of the same or nearly the same period as the natural vibration period of the system. The state of adjustment that produces resonance in a mechanical or electrical system.

These natural frequencies of a musical instrument are known widely as the harmonics of the specified instrument. If a second interconnected object or instrument vibrates or oscillates at that specified frequency then the first object can be forced to vibrate at a frequency higher than its natural harmonic frequency. This phenomenon is known as resonance i.e.

One object vibrating or oscillating at the natural frequency of another object forces the other object to vibrate at a frequency higher than its natural frequency. SwingOne of the familiar examples of resonance is the swing.

Product description Yes, Robot Alchemic Drive is yet another giant robot game, but this one is different, I swear. The main difference is in the way you control your robot-not from a cockpit inside the robot's skull, or from a dynamic third-person perspective, but by remote control from the point of view of a human character on the ground. Robot Alchemic Drive Review While Robot Alchemic Drive is sometimes hampered by its nostalgia, it successfully and entertainingly captures the feel of controlling a giant robot like no other game. While Robot Alchemic Drive is sometimes hampered by its nostalgia, it successfully and entertainingly captures the feel of controlling a giant robot like no other game has in the past. Robot Alchemic Drive, known in Japan as Gigantic Drive, is a PlayStation 2 video game developed by Sandlot and published by Enix. It was released in Japan and North America. In the game the player controls a giant robot called a Meganite, humanity's last line of defense against an extraterrestrial race called the Volgara. Robot alchemic drive.

It is common knowledge that the swing moves forward and backwards when pushed. If a series of regular pushes are given to the swing, its motion can be built.

The person pushing the swing has to sync with the timing of the swing. This results in the motion of the swing to have increased amplitude so as to reach higher.

Once when the swing reaches its natural frequency of oscillation, a gentle push to the swing helps to maintain its amplitude due to resonance. But, if the push given is irregular, the swing will hardly vibrate, and this out-of-sync motion will never lead to resonance, and the swing will not go higher. BridgeGroup of soldiers marching on the bridge are asked to break their steps very often because their rhythmic marching can set extreme vibrations at the bridge’s natural frequency. The bridge can break apart if the synchronized footsteps resonate with the natural frequency of the bridge.

One of the examples of the above is the Tacoma Bridge Collapse, where the frequency of the air matched with the frequency of the bridge leading to its destruction.To learn more about other related concepts of resonance, below are the links:.How to Calculate Resonant Frequency?A resonant frequency is the natural vibrating frequency of an object and is usually denoted as f with a subscript zero (f 0). Resonance is witnessed in objects that is in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.To find the resonant frequency of a single continuous wave, we use the formula. (v = λf)Where,.

v is the wave velocity. λ is the distance of the wavelengthDifferent Types of ResonanceThere are many types of resonance, and they are: Mechanical ResonanceMechanical resonance can be defined as the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system’s natural frequency of vibration (its resonance frequency or resonant frequency) than it does at other frequencies. The resonant frequency of a spring is calculated using the given formula.
