Chapter 15: Q.12 (page 414)

What is the difference between the driving frequency and the natural frequency of an oscillator?

Short Answer

Expert verified

The distinction is that in the instance of driving frequency, there is some external force, whereas in the case of natural frequency, there is none.

Step by step solution

01

Introduction

Frequency refers to the number of waves that pass through it at a given position in a given amount of time. If the time it takes for a waveform to travel is a second, the frequency is per second. If it takes an hour, the frequency is per hour.

The hertz unit is used to measure frequency.

02

Step 2:Explanation

When the oscillating system begins to oscillate at a set frequency foon its own ,

This frequency is referred to as natural frequency.

However, a system vibrating with a frequency fextdue to external excitation ,

This frequency is referred to as driving frequency..

03

Differentiation of frequency  

As previously stated, driving frequency is caused by external excitation, whereas natural frequency is caused by the system's oscillation when left to fluctuate naturally.

The difference is that there is an external force in the case of frequency, whereas it is not there in the case of natural frequency.

The pendulum shown in figure is pulled to a 10° angle on the left side and released.

a. What is the period of this pendulum?

b. What is the pendulum’s maximum angle on the right side?

It is said that Galileo discovered a basic principle of the pendulum—

that the period is independent of the amplitude—by using

his pulse to time the period of swinging lamps in the cathedral

as they swayed in the breeze. Suppose that one oscillation of a

swinging lamp takes5.5s.

a. How long is the lamp chain?

b. What maximum speed does the lamp have if its maximum

angle from vertical is 3.0∘?

A 200g ball is tied to a string. It is pulled to an angle of 8.0°and released to swing as a pendulum. A student with a stopwatch finds that 10oscillations take12s. How long is the string?

On your first trip to Planet Xyou happen to take along a 200gmass, a 40cm-long spring, a meter stick, and a stopwatch. You’re curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth, but you can’t find this information in your Visitor’s Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 31.2cm. You then pull the mass down 10.0cmand release it. With the stopwatch you find that 10oscillations take 14.5s. Based on this information, what is g?

A250g air-track glider is attached to a spring with spring constant 4.0N/m. The damping constant due to air resistance is 0.015kg/s. The glider is pulled out 20cm from equilibrium and released. How many oscillations will it make during the time in which the amplitude decays to e-1 of its initial value?
