Resonance Demonstrator Eccentric Load Gearbox Device Spring Vibrator Teaching

Description

Product description
Forced vibration and resonance demonstrator
This product is suitable for demonstrating forced vibration and resonance phenomena in high school physics teaching.
This product consists of a spring vibrator, a gearbox device with eccentric load, a oscillating plexiglass panel, a drawing board, a brush, and a base and rail control system.
The principle is that when the eccentric power of the eccentric is equal to the natural frequency of the plexiglass panel system supported by the spring, resonance occurs, and the amplitude is maximum.
When the frequency of the strategy power is not equal to the natural frequency of the panel system supported by the spring, the amplitude is reduced, and the difference between the frequencies is larger, and the amplitude is smaller. spring, resonance occurs, and the amplitude is maximum.
Size: Approx. 24.7m x 4.7cm x 4.5cm/9.7" x 1.8" x 1.7"
Instructions
1, can use student power
2. Turn on the power, press the button, the potentiometer will go to the initial position, the brush will record the amplitude of the amplitude on the drawing board, move the drawing board, and the amplitude of the rotating potentiometer will gradually increase, to the middle position, the amplitude is the largest, continue According to the rotary potentiometer, the amplitude gradually decreases and the experiment ends. After the art board has been degaussed, it can be used by children.
Matters needing attention and maintenance
1. The instrument should be placed flat.
2. During the experiment, the movement of the drawing board should be smooth and slow, the spring inside the brush, and the distance between the drawing board and the drawing board can be adjusted appropriately.
3. Wipe clean after use and keep it dry. A place where good girls are found.
