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.
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.
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
When there is reduction in amplitude over every cycle of vibration then the body is said to have?
This would be an example of damping or resistance present in the vibrating system.
What is the definition of resonance in science?
Resonance is the tendency of a system to oscillate with larger amplitude at some frequencies than at others. These are known as the system's resonant frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy. Resonances occur when a system is able to store and easily transfer energy between two or more different storage modes (such as kinetic energy and potential energy in the case of a pendulum). However, there are some losses from cycle to cycle, called damping. When damping is small, the resonant frequency is approximately equal to a natural frequency of the system, which is a frequency of unforced vibrations. Some systems have multiple, distinct, resonant frequencies.
Applications of critical damping?
critical damping is when the amount of damping is large enough for the system to return toequilibrium as fast as possible without performing oscillations. Hope thatHELPED
Damping coefficient for viscous fluids?
The damping coefficient ς is a parameter which determines the behavior of the damped system
Why damping is small in ballistic galvanometer?
to get critical damped system
What is use of cushion in hydraulic system?
to absorb the vibration damping.

When referring to mechanical terms what is damping?
Damping in mechanical terms means that there is a reduction in the amplitude of oscillation because the energy is being drained. The system is trying to to stop friction.
How damping progressively reduces the amplitude oscillations?
When energy is lost from the oscillating system, the amplitude of oscillationdecreases. When that happens progressively, we say that the oscillation is"damped". "Damping" is a description of the decrease, not its cause.
Advantage of critical damping over under damping and over damping?
A system that is critically damped will return to zero more quickly than an overdamped or underdamped system. Underdamping will result in oscillations for an extended period of time, and while overdamped things will return to zero without much (or any, I think) oscillations they will get there more slowly.
What is the approximate peak overshoot for a unity feedback system with damping factor 0.6?

What is negative damping?
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.
What are the different methods of damping used in analog indicating instruments?
Damping torque can be provided by: (a) air friction damping (b) fluid friction damping (c) eddy current damping. In air friction damping, a light piston moves with a very small clearance in air chamber. The piston moves against pressure of air in air chamber. In fluid friction damping, light varies are attached to spindle of moving system. The movement of spindle is suppressed due to fluid friction, Eddy current damping is one of the most efficient method of damping. It is based on the principle that whenever a sheet of conducting but non magnetic material like copper or aluminum moves in magnetic field, eddy currents are induced.
