When the outer side of the thumb touches the friction ring and clings to the arc surface, the long rod swings back and forth in the arc direction, centrifugal force is generated by the long rod, and the friction force generated by the centrifugal force acting on the friction ring can keep the long rod clinging to the thumb and not sliding down.
It should be noted that the radius of the arc surface is larger than 4cm, which means that the radius can approach infinity, that is, approach to a plane, and when the radius of the arc surface is too small, the long rod can roll easily and is not easy to be adsorbed outside the thumb.
In order to increase the entertainment, the long rod is made of a light-transmitting plastic tube, and further comprises:
a battery mounted within the long rod; can design into detachable construction, the convenient change.
The upper mercury switch is arranged at a position above the middle part in the long rod, and the contact part of the upper mercury switch faces the arc surface or the upward extending surface of the arc surface and inclines upwards;
the lower mercury switch is arranged at the bottom in the long rod, and the contact part of the lower mercury switch faces downwards;
a plurality of LED lamps installed in the light-transmitting plastic tube;
the battery supplies power to the LED lamps which are connected in parallel through the upper mercury switch and the lower mercury switch;
when the outer side of the thumb touches the friction ring and is tightly attached to the arc surface, and the thumb swings back and forth in the arc direction, the lower mercury switch circuit is switched on, the mercury in the upper mercury switch is influenced by centrifugal force, the gathering contact part is also switched on, and the plurality of LED lamps are lightened.
The contact part of the upper mercury switch faces the arc surface or the extending surface of the arc surface upwards and inclines upwards to prevent the LED from being lightened when the long rod is horizontally placed or vertically placed.
In order to increase the friction force, a plurality of small convex blocks are arranged on the arc surface of the friction ring, and the friction force between the friction ring and the thumb can be increased by utilizing the small convex blocks.
Preferably, the friction ring is made of sponge.
In order to increase the weight and generate larger centrifugal force, a transparent sealing bag is arranged in the light-transmitting plastic pipe, and tap water is filled in the sealing bag.
Preferably, the transparent sealing bag has a cylindrical shape.
Preferably, the upper mercury switch is inclined at an angle a of 15 to 30 degrees.
Preferably, the arc radius of the arc surface is 4-8 cm.
The centrifugal force demonstration device has the advantages of simple structure, low cost, capability of demonstrating centrifugal force and entertainment.
