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.
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.
Yes, but it involves a second order differential equation. Using the mass, spring constant and damping constant any physical object or assembly's damping ratio can be calculated. In the design of the vehicle the damping ratio was determined by the engineers at the automaker depending on the type of car. A sports car would have a higher damping ratio (maybe 0.7 or so) than a cushy luxury car. Over time the damping ratio will change…

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…

All 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.
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.
