In various communities, parks and children's playgrounds, there is a small device called a seesaw. The shaft is placed in the middle of the long and thick planks, and then placed on the pillars. The two kids sit on both ends and take turns on the pedals, which makes one end pick up, the other end fall, so repeatedly. Small seesaw is very popular with children.
The children seesaw is a multi-person (two or more) children's play equipment. Sitting on the seesaw equipment, one person sits on one side, one person goes up, one person goes down, and the up and down movement can give the child a kind of happiness.
The principle of the seesaw play equipment is to use the principle of leverage. The pressure on the seesaw is the power and resistance. The distance from the fixed point of the person to the seesaw is the force arm. The acceleration of gravity causes one up and down, and the acceleration of gravity is higher than that of the lower one, so the high one drops, and at the same time, the lower one is tilted under the action of the lever principle, and thus circulates.
We all know that playing the seesaw is a playful children's play equipment that needs to be matched to play, so this is to foster a cooperative spirit between children.
