Description

грузом 3 и колебаний децентрованного шара 4, перемещающегос по поверхности А груза 3,with load 3 and oscillations of the decentered ball 4 moving along the surface A of the load 3,

Если же игрушку перевести в горизонтальное положение, как на фиг, 2, то здесь все зависит от того, в каком положении относительно груза 3 будет располагатьс центр т жести децентрованного шара 4. Если центр т жести будет располагатьс ближе к грузу 3, то физика происход щего будет определ тьс левой частью соотношени , приведенного выше, и игрушка вернетс в горизонтальное положение. Если же центр т жести будет расположен дальше от груза 3, то определ тьс поведение будет правой частью соотношени и игрушка останетс в горизонтальном положении, т.е. л жет спать. И, поскольку положение центра т жести носит веро тностны и характер, то такой же характер будет.носить и засыпание игрушки.If the toy is placed in a horizontal position, as in FIG. 2, then everything depends on the position in which the center of gravity of the deformed ball 4 is located relative to load 3. If the center of gravity is closer to load 3, then the physics The toy will be determined by the left side of the ratio above, and the toy will return to the horizontal position. If the center of gravity is located further from load 3, then the behavior will be determined by the right side of the relationship and the toy will remain in a horizontal position, i.e. l'm going to sleep. And since the position of the center of the body is of likelihood and character, the same will be the nature of the falling asleep toy.

Claims

Claims of the invention A toy comprising a body made hollow and having upper and lower spherical bases, and a load mounted in a lower spherical base, characterized in that, in order to increase the activity, a spherical load is placed inside the body with the possibility of free movement. which is displaced relative to its center of roll, while the body with the load and the spherical load have masses

m (I- / M Lt (1 + D), where M is the mass of the hull with a load: m is the mass of a spherical load, L is the distance from the intersection point

the normal, lowered from the center of body weight of the body with a load on the tangent plane to the upper and lower spherical bases, to the point where this plane touches the lower spherical base;

I is the distance between the points of contact of the tangent plane by the spherical bases;

The distance between the center of the body and the rolling center of the spherical load.
