Specification: 38cm*14cm*43cm/14.9*5.5*16.9in
Material: plastic
Uses: physical laboratory equipment
Instructions
Place the bracket horizontally on the table, so that the five pendulum balls are at rest, and then change the pendulum length of the pendulum pendulum so that its length is the same as one of the pendulum lengths, so that the pendulum pendulum and the crossbar periodically swing and the other pendulum passes through them. The same swaying amplitude of the suspension point is more and more large, and the other four sway pendulums with different pendulum and motion pendulum amplitude are small, and the contrast is very obvious.
Adjust the swinging pendulum to do the same step of the experiment. The demonstration shows that resonance occurs when the natural frequency of the vibration syis equal to the actuation frequency.
Precautions
When using the instrument, it should be handled gently. After use, store it in a cool and dry place without corrosive gas.
Note:
Because it is a manual measurement, the product size has a small range error of 0.5-1cm, please refer to the actual product, please understand.
