Lets assume that a system(a sensitive balance) is designed in such a way that there is a minimum damping.If one keeps mass on its pans and if masses slightly unbalance,The balance will keep oscillating for very long time.This is unreliable system.
Thats why damping is nessary

∙ 12y agoAll members, structural or masonry, made with cement crack. The number, size and inter-conectivity of such cracks dictates the permeability of a member. When water permeates through such member, it slowly starts showing up on the other side as damping. Applying waterproofing chemical on the exposed side of such member can control damping.

How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
What is hysteresis effect?
In simplest terms, hysteretic damping is the energy lost in materials due to friction between molecules, and is related to displacements during vibration. It is also known as 'material damping.'
What does an Ohaus triple beam balance do?
Ohaus triple beam mechanical balances are used for determining the exact weight of an item. It uses magnetic damping to speed up the process of weighing.
What is damping error in gyro compass?
This error is present in a compass which is damped in tilt. A compass damped in tilt always settles east of the meridian and above the horizon in NH, and vice-versa. Its magnitude depends on the observer's latitude, Sin( error ) α Tan( latitude ) At equator, the error is nil. The error is eastward in all northernly latitudes, and vice-versa. For the purpose of damping error, a latitude rider / adjuster is provided with the gyro compass which shifts the lubber line equal to the amount of error in the appropriate direction.
How are the carbon nitrogen and oxygen cycle necessary for life?
carbon is necessary for making all organic chemicalsnitrogen is necessary for making proteinoxygen is necessary for aerobic respiration
What is negative damping?
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.
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.
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
What is the definition of viscous damping and viscous damping coefficient especially in Civil Engineering.?
== Answer }
What is geometric damping?
Geometric damping is also called radiation damping. It is defined as energy radiation into a surrounding medium. Damping is defined as energy dissipation property of structures and materials that are put through time-variable loading.
What is damping level?
In the damping level the level view and vertical spindle are crossed together...
How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
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
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.
Damping coefficient for viscous fluids?
The damping coefficient ς is a parameter which determines the behavior of the damped system
What are the ratings and certificates for Damping malam - 2010?
Damping malam - 2010 is rated/received certificates of: Singapore:PG
Why negative feedback is necessary in closed-loop control systems?
Feed back generated can be used to help alter the gain in the system to ensure marginal stability or critical damping
