Center of gravity balance demonstration ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
Balanced representation of objects in the image of a bird to balance its focused in the mouth, the structure is very light, about the weight evenly and so on. Its primary feature is the balance; Therefore, in the course of using the balanced birds must be careful to balance the effect will be. Through this experiment is that students can understand the balanced condition.
Bird balance is based on the center of gravity to do, there are two iron bird body, is used to determine the critical center of gravity position, the iron is located near the wings of a bird, so the focus falls on the whole bird on the beak-, on the base or a pivot, it is balanced.
Find the center of gravity of the object methods are: (1) the geometry of the rules of gravity is diagonal intersection; (2) round the center of gravity in the center; (3) the center of gravity of irregular flat line method can be used to hang find out: the intersection of the two lines is linked to the plane of the center of gravity of irregular, the specific method (shown in Figure 2): C is the intersection of the center of gravity of irregular flakes.
Products by the equilibrium bird, pyramid bracket, square bracket, base composition.
