Damping is any effect, either deliberately engendered or inherent to a system, that tends to reduce the amplitude of oscillations of an oscillatory system.

In physics and engineering, damping is mathematically modelled as a force with magnitude proportional to that of the velocity of the object but opposite in direction to it. Thus, for a simple mechanical damper, the force F is related to the velocity v by

F = -Bv

where B is the damper constant.
This relationship is perfectly analogous to electrical resistance. See Ohm's law.

In playing stringed instruments such as guitar or violin, damping is the quieting or abrupt silencing of the strings after they have been sounded, by pressing with the edge of the palm, or other parts of the hand such as the fingers on one or more strings near the bridge of the instrument. The strings themselves can be modelled as a continuum of infinitesimally small mass-spring-damper systems where the damping constant is much smaller than the resonant frequency, creating damped oscillations (see below). See also Vibrating string.

By Building Plant Room, do you mean a room that contains communications equipment? If so, the racks of equipment are frequently mounted on very stiff springs to help prevent damage in an earthquake or other dissaster.

present day Victorian, i admire including distinctive subjects to each and each room. i exploit a brilliant style of stained glass (additionally very useful for conserving the sunlight out, i'm very comfortable to the sunlight) wood, delicately carved furnishings and pink hardwood flooring (simpler to scrub while the fowl poops on it)

No I won't.

If you hand that in, though, they might suspect you've done your own homework for a change.
