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.
Why does sound get quieter?
Because of air damping.
Calculation of damping ratio for car suspension?
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 as the components age. The most obvious is the bouncy feeling when you don't replace your struts or shocks as intended. That's when your tight sports car's suspension starts to behave like a 70's Buick. You just lowered your damping ratio without knowing it.
How is inertia related to pendulums?
Inertia is a massive object's resistance to change. It should be obvious then that mass is directly proportional to how long the pendulum swings before coming to rest, since more mass means harder to stop. Mathematically, you'll find this dependence on mass in the damping equations of pendulums.
Is 120-xL proportional or not proportional?
It is an expression, not an equation and so cannot be proportional nor non-proportional.
What is the unit of damping co efficient?
The unit of damping coefficient is Ns/m, which represents the force required to bring a unit velocity proportional to the damping coefficient to a stop in a unit distance.
Why is sharpness of resonance inversely proportional to the damping force?
The sharpness of resonance is inversely proportional to the damping force because damping reduces the amplitude of oscillations in a system, leading to a broader resonance peak. Higher damping forces cause energy to be dissipated more quickly from the system, resulting in a less pronounced peak at the resonant frequency.
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.
How can you decrease the degree of damping?
You can decrease the degree of damping by reducing the amount of friction or resistance in the system. This can be achieved by using lighter weight damping materials, adjusting the damping coefficients, or using a less viscous damping fluid.

What is damping level?
In the damping level the level view and vertical spindle are crossed together...
Which type of damping occurs in automobile's suspensions?
The two most common types of damping in automobile suspensions are hydraulic damping and gas damping. Hydraulic damping uses fluid to dissipate energy and control vibrations, while gas damping uses gas-filled chambers to absorb and reduce shock. Both types work to provide a smoother and more controlled ride for the vehicle.
Damping ratio of higher order systems?
In higher order systems, the damping ratio is determined by the ratio of the actual damping in the system to the critical damping value corresponding to the highest order term in the system transfer function. The damping ratio influences the system's response to a step input, affecting overshoot and settling time. High damping ratios result in quicker settling times but may lead to more overshoot.
What is the formula for Damping frequency?
The formula for damping frequency is Ο_d = Ο_n * sqrt(1 - ΞΆ^2), where Ο_d is the damping frequency, Ο_n is the natural frequency, and ΞΆ is the damping ratio. It represents the rate at which the amplitude of a damped oscillator decreases over time.
What is a gradual loss of amplitude of an oscillator called?
This is known as damping. Damping refers to the gradual decrease in the amplitude of an oscillator's motion due to the energy dissipation in the system.
