Why does the amplitude of free vibration gradually diminish in a particular system?

Explanation: Since a certain amount of energy is always dissipated while overcoming the resistance forces, In damped vibrations, the amplitude of the resulting vibration gradually diminishes. This is due to the reason that a certain amount of energy is always dissipated to overcome the frictional resistance.

Why does the amplitude of a vibrating body continuously decrease?

Body continuously losses energy due to frictional force of the surrounding medium in damped oscillations, therefore the amplitude of body continuously decreases.

Why is the amplitude of damped vibration gradually decreases?

(iii) The amplitude of vibrations gradually decreases due to the frictional (or resistive) force which the surrounding medium exerts on the body vibrating in it. As a result, the vibrating body continuously loses energy in doing work against the force of friction causing a decrease in its amplitude.

How can the amplitude of vibration be reduced?

Clearly, we can minimize the vibration amplitude of the mass by making . We can do this by making the spring stiffness as small as possible (use a soft spring), and making the mass large. It also helps to make the damping small.

Which type of vibration amplitude of vibration goes on decreasing every cycle?

damped vibration
When there is a reduction in amplitude over every cycle of vibration, the motion is said to be damped vibration.

When the energy of vibrating system is gradually dissipated by friction and other resistance The vibration is said to be?

When the energy of a vibrating system is gradually dissipated by friction and other resistances, the vibrations are said to be damped. The vibrations gradually reduce or change in frequency or intensity or cease and the system rests in its equilibrium position.

What do you understand by free vibrations of a body?

Free vibration of the body is the kind of vibration when a force is exerted on the body only at once and the body starts to vibrate at its natural frequency.

What do you understand by free vibrations of a body 2?

Solution 2 The vibrations of a body in the absence of any external force on it are called the free vibrations. Eg.: When we strike the keys of a piano, various strings are set into vibration at their natural frequencies.

Why does the amplitude of oscillation decreases with time?

The amplitude of an oscillation pendulum decreases with time become of friction due to air oscillation damp down after same time becomes of friction force acting on it This is known as damping is the term used describe the loss of energy with each cycle of an oscilation The octure because of loss of heat that to air …

Why the amplitude of oscillation decreases afternoon due to damping?

Damped oscillations means a decrease in intensity of oscillations with time. The force of friction retards the motion so that the system does not oscillate indefinitely. The friction reduces the mechanical energy of the system, the motion is said to be damped and this damping reduces amplitude of the vibratory motion.

How can resonance amplitude be reduced?

How to Avoid Resonance

1. Adding stiffness increases the natural frequency.
2. Adding mass decreases the natural frequency.
3. Increasing damping reduces the peak response but widens the response range.
4. Decreasing damping increases the peak response but narrows the response range.

In which type of vibration amplitude of vibration goes on decreasing every cycle?

When there is a reduction in amplitude over every cycle of vibration, the motion is said to be damped vibration.

What causes a decrease in the amplitude of a vibration wave?

Vibrations are induced when the system is excited with some force. The gradual decrease in amplitude of systems corresponds to practical stable systems which have some damping associated with it. This damping could be Internal damping (loss factor) or external damping (friction,drag).

Can we predict the frequency of vibration without damping?

One important conclusion is that if the energy dissipation is low, the system will vibrate. Furthermore, the frequency of vibration is very close to that of an undamped system. Consequently, if you want to predict the frequency of vibration of a system, you can simplify the calculation by neglecting damping.

What is meant by gradual decrease in amplitude?

The gradual decrease in amplitude of systems corresponds to practical stable systems which have some damping associated with it. This damping could be Internal damping (loss factor) or external damping (friction,drag).

How does energy dissipation affect the vibrating system?

If the trajectory approaches the origin, the system is decaying to its equilibrium configuration. We now know the effects of energy dissipation on a vibrating system. One important conclusion is that if the energy dissipation is low, the system will vibrate. Furthermore, the frequency of vibration is very close to that of an undamped system.
