Product Introduction
1. The archimedes principle experimental device is composed of dynamometer, plastic bucket, plastic cylinder and overflow cup.
2. The left range of the demonstration dynamometer is 0-2N, the minimum division value is 0.1N, and the maximum division value is 0.5N. The right scale mark is consistent with the left scale mark, and there are two cursor pointers.
3. The total mass of the plastic barrel and plastic cylinder is 140g. There are three volume and volume bisectors on the barrel and column arm, and the line width is 1mm. The volume of plastic bucket is 100ml.
4. The lower opening height of overflow tube of overflow cup shall not be less than 70mm.

1. Verify Archimedes' principle:
Put the plastic cylinder in the plastic bucket, and the two closely match the volume of the plastic bucket, that is, the volume of the plastic cylinder.
Hang the plastic bucket (with plastic cylinder inside) on the dynamometer hook to read its weight.
Take the plastic cylinder out of the plastic bucket and hang it on the hook under the plastic bucket, you can see that the pointer indication remains unchanged. At this time, the reading is g.
Then diffuse the cylinder into the overflow cup containing water, and the indicated value of the dynamometer gradually decreases. From this, it can be seen that the object immersed in the liquid is subject to buoyancy, and the buoyancy can be determined by the difference between the two readings of the pointer. When the cylinder is fully immersed, it will suffer a large amount of buoyancy.
The overflowing liquid will be disposed at the overflow nozzle after the overflow cup is immersed in the plastic cylinder
A cup) is poured into the plastic barrel, and the visible pointer returns to the initial reading, proving that the buoyancy of the plastic cylinder is equal to the weight of the liquid it discharges.
It is concluded that the object immersed in liquid is subject to upward buoyancy, and the buoyancy is equal to the weight of the liquid discharged by the object. This is Archimedes' law.
2. Weigh any measured object with a dynamometer. Calculate its mass, and then immerse it in the overflow cup. Use a dynamometer to weigh the liquid discharged from the overflow cup and convert it into volume V. The density of an object of any geometric shape to be measured can be obtained from the following:
Namely:
- According to the above principle, the right demonstration shows the determination of the density of different liquid objects in the ship's load line.
Product feature and application
Archimedes principle tester is used to verify Archimedes principle in middle school physics and measure the density of objects.
Maintenance and precautions
1. When using, hang the dynamometer vertically, and adjust it through the upper thread to make the indicator point to the "0" position scale line.
2. After use, place the dynamometer flat in the box to avoid being squeezed by organisms.
3. Wipe the plastic cylinder of the plastic bucket and the overflow cup clean after use.
