### 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… Full Answer

### What is the minimum damping ratio in fine boring spindle?

the fine boring spindle using CBN tools creates chatter . is it because less damping ratio of spindle? the bore is 100 mmdia . L/D ratio is 5

### What is Impedance ratio?

Transformer Z-ratio = (Zpri / Zsec) = (Vpri / Vsec)2 It could also be the damping factor DF = Zload / Zsource The damping factor DF is the load impedance Zload (input impedance) divided by the the source impedance Zsource… Full Answer

### What is the approximate peak overshoot for a unity feedback system with damping?

According to some references I checked, the overshoot will be: 100*exp[z*pi/sqrt(1-z^2)] where "z" is the damping ratio This is about 9.5% at z=0.6 Source(s):

### 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.

### What is the damping coefficient?

I wanted to know what damping was not answer it!!!

### What is damping?

Damping is the attenuation of vibrations or oscillations.

### What is negative damping?

It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.

### Applications of critical damping?

critical damping is used in robotics.

### 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...

### What is meant by critical damping?

critical damping is when the amount of damping is large enough for the system to return to equilibrium as fast as possible without performing oscillations. Hope thatHELPED

### 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

### How does surface area affect damping of an oscillation?

The larger the surface area, the larger the damping of an oscillation

### What is hysteresis damping?

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 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… Full Answer

### Damping coefficient for viscous fluids?

The damping coefficient ς is a parameter which determines the behavior of the damped system

### What is damping coefficient of fluids?

really don't know...the damping coefficient of commnoly used dampers is a grey area

### What are the ratings and certificates for Damping malam - 2010?

Damping malam - 2010 is rated/received certificates of: Singapore:PG

### 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… Full Answer

### How do you get -12 decibels?

Decibel is a factor or a ratio and no unit. If you have 1 volt and you damp it to 1/4 volt then you will get a damping of 12 dB. Voltage daming = 20×log (1/4) = (-)12 dB.
