What is damping and how does affect resonance?
Damping is the dissipation of energy in a vibrating system. It affects resonance by reducing the amplitude of vibrations and slowing down the rate at which energy is exchanged between the system and its surroundings. Higher damping decreases the peak amplitude of resonance and widens the resonance frequency band.
Is it possible to have damped oscillations when a system is at resonance?
Resonanceis aforcethat remains in a opposite position.It is also observed in physical media such as strings and columns of air. Any waves traveling along the medium will reflect back when they reach the end. It is possible to have damped oscillations when a system is at resonance.
What is the unit of damping co efficient?
The unit of damping coefficient is Ns/m, which represents the force required to bring a unit velocity proportional to the damping coefficient to a stop in a unit distance.
Why the resonance curve broadens for higher damping?
Higher damping causes energy to be transferred more quickly between the system and its surroundings, resulting in a faster dissipation of energy. This leads to a broader resonance curve because the system reaches its maximum amplitude at a wider range of frequencies before dissipating the energy.
Why are damping devices used on machinery?
Damping is the resistance offered by a body when a system is in vibration. But the basic use of a damper(damping) is to help reduce the oscillations or vibrations.we can also conclude that we use damping to slow down the effect of a moving part.Damping controls the amplitude of vibrations just to avoid resonance conditions.

What is the Q factor in RLC circuit?
It is related to damping in the circuit using a resistor. Q is inversely proportional to the resistor(R). So if the value of resistance is high, there is a greater damping and the value of Q will be low. if resistance is low, there is small damping and Q will be high. when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large. Go do some research on the graphs and the formula of Q factor to understand it better.
Is it possible to have damped oscillation when asystem is at resonance?
Yes. You can have damping, independently of whether there is resonance or not.

HOW CAN RESONANCE COLLAPSE BRIDGES?
Resonance can collapse bridges if the frequency of vibrations from moving vehicles matches the natural frequency of the bridge structure, causing it to oscillate and eventually fail. This phenomenon, known as mechanical resonance, can lead to the accumulation of stress and strain that weakens the bridge's support structure, eventually causing it to collapse. Structural damping or modification of the bridge's design can help to prevent resonance-induced failures.
What are the methods of avoiding resonance?
Changing the material properties of the structure to shift the resonance frequency. Adding damping materials or devices to dissipate vibration energy. Using vibration isolators to decouple the vibrating system from its surroundings. Reducing the force excitation causing the resonance.
What is gain resonance?
Gain resonance occurs when a system or component amplifies a specific frequency or range of frequencies, causing an increase in amplitude at those frequencies. It can lead to unstable behavior and oscillations in systems, and it is commonly observed in electronic circuits and control systems. To address gain resonance, designers often incorporate damping techniques or use filters to attenuate the resonant frequencies.
What is negative damping?
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.
