With this demonstrator, you can measure and feel the weight of ordinary objects as if they were on other planets, the Sun, or under some kind of overload.
The operating principle is based on the condition of equality of moments of forces for equilibrium relative to the center of rotation F1 ⋅ L1 = F2 ⋅ L2.
The main element is a rod with a center of rotation. One arm of the rod is balancing, the other is measuring with specially calculated holes (from 1 to 10) and points for hanging weights. The holes for hanging weights are marked with arrows ^.
Values ​​of the holes:

acceleration of gravity on Earth g = 9.81 m/s²

1. Sun 27.85 g
2. Short-term overload experienced by military aircraft pilots, an ordinary person loses consciousness after a few seconds 12 g
3. Overload during landing of the Space Shuttle 3 g
4. Jupiter 2.528 g
5. Overloads that passengers of civilian airliners can experience 2 g
6. Venus 0.906 g
7. Mars 0.394 g
8. Acceleration of a car accelerating to 100 km / h in 8 seconds 0.354 g
9. Io (moon of Jupiter) 0.183 g
10. Moon 0.165 g

For the balancing arm, use a stud M6, nuts and any suitable weight.
The center of gravity of the entire rod must coincide with the center of rotation.
The base is any strong plate 200 mm * 600 mm
Fastening screws M4 and nuts for them 4 pcs.
Paper clips, pen rod.

Warning: do not weigh objects weighing more than 70 grams in position 1 (Sun) and 2 (12g), because the large forces arising in this case can break the structure.

For more accurate measurements, it is advisable to use hand scales with an accuracy of 1 gram.
