Description
- a cylinder with a mass of about 0.17 kg, one end of the set guide rod, and the guide rod is mounted in the middle of a vertical shaft that can be flexibly rotated
- The other end of the guide is equipped with a gold-adjustable balance body, the guide rods can be adjusted on both sides, and a horizontal spring is connected between the cylinder and the vertical shaft.
- The lower end of the cylinder protrudes downward with a radius indicator that is opened by a metal piece, and the knurled portion at the top of the vertical shaft is used for finger swaying.
- This instrument is also equipped with a weight body and spring adjustment rod with a mass of about 50 grams.
- Used to change the mass and spring rate. At the time of the experiment, a 500-gram spring was called.
Precautions:1. The base must be balanced and kept level when the instrument is in use.2. Before using, you need to add a little oil to the guide rod at the end of the cylindrical body to reduce friction.3. When the shaft is tilted, try to apply force evenly and periodically.4. The instrument should be stored in a ventilated and dry place to prevent corrosion of the surface coating.
