## Does damping affect resonance?

The effect of damping on resonance graph: The amplitude of the resonance peak decreases and the peak occurs at a lower frequency. So damping lowers the natural frequency of an object and also decreases the magnitude of the amplitude of the wave.

**What is resonance in harmonic motion?**

Resonance: the large amplitude vibration that results when an oscillator is driven at its natural frequency of vibrations.

**What is the frequency condition of resonance phenomenon in damped system?**

When damping is small, the resonant frequency is approximately equal to the natural frequency of the system, which is a frequency of unforced vibrations.

### What is damped harmonic oscillator and their condition?

The damped harmonic oscillator is a classic problem in mechanics. It describes the movement of a mechanical oscillator (eg spring pendulum) under the influence of a restoring force and friction. This article deals with the derivation of the oscillation equation for the damped oscillator.

**How damping affects the sharpness of resonance?**

The sharpness of resonance increases with an increase in damping and decreases with a decrease in damping.

**How do you reduce resonance?**

How to Avoid Resonance

- Adding stiffness increases the natural frequency.
- Adding mass decreases the natural frequency.
- Increasing damping reduces the peak response but widens the response range.
- Decreasing damping increases the peak response but narrows the response range.

## What is the condition for resonance?

The conditions to produce resonance in an object are: The object must have a minimum of one natural frequency of vibration. The object must be driven by an external force of vibration. The frequency of the external vibrating force must be similar to the object’s natural frequency of vibration.

**Which condition will result in resonance?**

Resonance only occurs when the first object is vibrating at the natural frequency of the second object.

**What are the characteristics of damped oscillation?**

The essential characteristic of damped oscillator is that amplitude diminishes exponentially with time. Therefore, oscillator energy also diminishes. In the phase space (v-x) the mass describes a spiral that converges towards the origin. If the damping is high, we can obtain critical damping and over damping.

### What is damped harmonic oscillator equation?

Fd = – pvWhere,v is the magnitude of the velocity of the object and p, the viscous damping coefficient, represents the damping force per unit velocity. The negative sign indicates that the force opposes the motion, tending to reduce velocity.
