IN THE SEE –SAW GAME, WHY THE SEATS ARE GOING DOWN IN ONE SIDE, WHEN THERE IS NO PERSON, THOUGH THE SEATS IN AN EQUAL POSITION?
The structure of the sea-saw and the structure of the balance are the same and equal. First and foremost, the seats are not in equal weight, accurately. There may be small differences. Therefore, with a view to measure scientifically, we use the balance made for the specific purpose. Secondly, frictions in the spindle area with which the see-saw boards are joined along with the legs of the game-tool bend incidentally towards any one of the sides. Further dust and soil may go inside the spindle area and cause a sealing may prevent the boards without easily bending. If you apply oil in that area and reduce the friction, it would be easy to play.
