WebFORCED OSCILLATIONS AND RESONANCE Suppose now that instead of allowing our system to oscillate in isolation we apply a "driving force". For example, in the case of the (vertical) mass on a spring the driving force might be applied by having an external force (F) move the support of the spring up and down. WebFORCED OSCILLATIONS The phenomenon of setting a body into vibrations with the external periodic force having the frequency different from natural frequency of body is called forced vibrations and the resulting oscillatory system is called forced or driven oscillator.

WebResonance is a special case of forced vibrations in which the externally applied periodic force has the same frequency as the natural or free vibration frequency of the vibrating body. If a vibrating system is subjected to the action of an external periodic force, the system executes what is referred to as forced oscillations. WebJun 16, 2024 · (a) In forced oscillations, a body oscillates under the effect of an external periodic force of frequency other than its natural frequency. (b) In resonant oscillations, the frequency of the periodic force is always equal to natural frequency of oscillation of the object. Answer.

WebJun 16, 2024 · By forcing the system in just the right frequency we produce very wild oscillations. This kind of behavior is called resonance or perhaps pure resonance. Sometimes resonance is desired. For example, remember when as a kid you could start swinging by just moving back and forth on the swing seat in the “correct frequency”? WebApr 7, 2024 · Forced Oscillations: When a body is acted upon by a force of frequency different from the body’s natural frequency, the body is said to undergo natural oscillations.
