Determine the room’s air temperature‚ and also measure the diameter of the glass tube. Record the data. 3. Select a tuning fork and record the frequency (in Hz) in the data table. Record the data. 4. Strike the tuning fork against a rubber stopper‚ and hold it just above the opening of the glass tube. Raise or lower the glass tube/fork until the loudest sound is heard.

The concept of resonance was the broad general idea that enlightened this particular lab. A natural vibrating frequency occurs when a tuning fork vibrates after a student struck the tuning fork. When a tuning fork is struck and placed near the column of air‚ it creates a standing wave. A resonance is created when the frequencies of tuning fork and the column of air are equal to each other. For the resonance to occur‚ the distance between the top of the tube and the water must be either ¼ of the wavelength

forced to vibrate at the excitation frequency. If the frequency of excitation coincides with one of the natural frequencies of the system‚ a condition of resonance is encountered‚ and dangerously large oscillations may result. The failure of the major structures such as bridges‚ buildings or airplane wings is an awesome possibility under resonance. Thus‚ the calculation of the natural frequencies is of major

ultrasonic motor INTRODUCTION All of us know that motor is a machine which produces or imparts motion‚ or in detail it is an arrangement of coils and magnets that converts electric energy into mechanical energy and ultrasonic motors are the next generation motors. In 1980‚the world’s first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed‚ high torque
