How can one determine the damped natural frequency from a graph?
To determine the damped natural frequency from a graph, one can identify the peak of the response curve and measure the time it takes for the amplitude to decrease to half of that peak value. The damped natural frequency can then be calculated using the formula: damped natural frequency 1 / (2 damping ratio time to half amplitude).
Define damped oscillation?
Any oscillation in which the amplitude of the oscillating quantity decreases with time is referred as damped oscillation. Also known as damped vibration, http://www.answers.com/topic/damped-harmonic-motion
What is the differences between damped and undamped oscillations?
damped vibrations:in damped vibrations the amplitude of the signal decreases with respect to timeundamped vibrationsin undamped vibrations the amplitude of the signal remains constant with respect to time
Is a pogo stick a critically damped system?
No, a pogo stick is not a critically damped system. It typically exhibits underdamped behavior when bouncing, with oscillations that gradually decay over time due to damping effects. The damping in a pogo stick is usually not enough to make it critically damped.
What is critical resistance in circuit theory?
With respect to an RLC circuit, the critical resistance is the resistance which would critically dampen the circuit. This means a resistance lower than the critical resistance would create an under-damped situation, and higher than the critical resistance would create an over-damped situation. An underdamped circuit will ocillate, an overdamped circuit will decay exponentially over a long period of time. The critically damped circuit will immediately decay to zero (time dependent on the values of the circuit elements)
When there is a reduction in amplitude over every cycle of vibration then the body is said to have?
Damped vibration. This occurs when energy is gradually dissipated, causing a decrease in amplitude over time. It is common in systems with friction or damping mechanisms.
Relation between relaxation time and mean collision time?
The relaxation time is related to the mean collision time through the expression: relaxation time = mean collision time / (1 - f), where f is the fraction of collisions that result in thermalization. The mean collision time represents the average time between particle collisions, while the relaxation time is the time it takes for a system to reach thermal equilibrium after a perturbation.
What is momentum relaxation time?
Momentum
Write the equation to represent a damped oscillation?
(Amplitude)at time=t = (Max) x cos[ (2 pi x frequency) + (phase angle) ] x e-time/time constant
What do you understand by relaxation allowance?
When working under harsh environmental conditions such as working in open air, allowances must be granted to the workers. Usually these take the form of relaxation allowances. This is additional time to relax to make up for working under excessive environmental factors such as heat, humidity, noise, dirt, lighting intensity and wet conditions.

Why collision time and relaxation time are not equal in anisotropic medium?
average time, an electron spends between two successive collision, is called relaxation time and time spent by electron at point of contact, is called collision time
What is R and R time?
Rest and Relaxation or, Rest and Recreation.
