Why is sharpness of resonance inversely proportional to the damping force?
the further the frequency from the resonant one, greater would be the damping effect, hence greater the sharpness the lowre is the damping effect
Why the resonance curve broadens for higher damping?
such a simple one, please dont make a mockery of a question
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.
Is Natural frequency and Resonance of a Cantilever Beam will be same?
The natural frequency of an undamped beam is the same as the resonant freqency. In the case of damping the Resonant_Frequency = Natrual_Frequency * sqrt( 1 - DampingRatio2)
How is light damping achieved?
The amplitude of resonant oscillations can be reduced by damping.Light damping reduces oscillations slowly.Heavy damping reduces oscillations quickly.Critical damping stops the oscillation within one cycle.The graph above shows light damping.
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 does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
How does resonance affect the sound quality of an instrument?
Resonance does not affect a violin. Resonance is the violins ability to vibrate with the tone that is played. With a high resonance, a violins sound will be heard long after the note is played. With a low level of resonance, a violin will sound dull and immature. Resonance affects the tone quality of a violin, but the violin has a direct relationship to its resonance.

How does the shape of the shorline affect a tide?
The shape of the coastline affect tides because of resonance. Resonance changes normal tide occilations. (see in the section of resonance, Hydrographic Volume II, Tide and Tidal Stream)

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.
What is negative damping?
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.

The amplitude of resonant oscillations can be reduced by damping.Light damping reduces oscillations slowly.Heavy damping reduces oscillations quickly.Critical damping stops the oscillation within one cycle.The graph above shows light damping.
Does the size of a wine glass affect how much sound is needed to break it?
Sometimes it can do. But most of the time is shouldn't really affect it. If it does, It will affect it slightly. If the glass contains liquid it will most certainly make a big difference, as the liquid will absorb resonance, such as vibrations (pressure waves). If a glass exhibits resonance (a clear tone when struck or tapped it exhibits resonance) it can be shattered by using sound waves at that frequency. If it does not exhibit resonance ( a dull thud when flicked) it will require a great deal more sound energy to shatter. Resonance can be affected by liquid in the glass or the composition (good crystal versus everyday thick glasses)
