AParticulate apart from distance of rotating shaft etc.The angular momentum L of (Tom.D., Advanced Physics for HongKong-Volume I:Materials and Mechanics, John Murry, pp.165-184,1992.) gyro is L=I ω, and ω is an angular speed here.According to equation E=1/2MR
2ω
2+ 1/2Mv
2, M is a quality here, ω is an angular speed, and v is a linear velocity, and for two objects with the same angular velocity rotation, the object with big the moment of inertia has bigger kinetic energy E, and bigger kinetic energy can increase the time of rotation.Center of gravity is the geometrical property of all objects, and is the mean place of a weight of object.If object has line of symmetry (or plane), center of gravity is located on this line of symmetry.For the solid block of homogeneous material, center of gravity is the mean place of actual size.For the rectangular block of one 50 (length) * 20 (wide) * 10 (height), its center of gravity is positioned at point (25,10,5).(referring to: Glenn Research Center, NationalAeronautics and Space Administration, 2006, http:www.grc.nasa.gov/www/k-12/airplane/cg.html).For example, the center of gravity of gyro 10 is positioned on its rotating shaft.
In one embodiment, gyro 10 has following size: highly be 70mm; The maximum gauge of main part is 45mm; The height of main part is 38.2mm; The height of outside axis body is 29mm; Distance from center of gravity to the main part top is 12.8mm; And gross weight (not being with cotton rope) is 90g.In this embodiment, tip 16, axis body 20 and 30, main part 12, disk 42, sleeve 24 and annular weight 48 can be made by above-mentioned definite material.In such an embodiment, distance " a " is 41mm, and distance " b " is 29mm, and ratio a/b is 1.41: 1.At equation I=MR
2In (I is the inertia of gyro here, and M is a quality), the moment of inertia that its center of gravity is positioned at the gyro at rotating shaft place is 4,675,000gmm
2When center of gravity is positioned at or adjacent grooves, a/b ratio are found the angular speed and the kinetic energy that can improve gyro 10, thereby have increased the rotational time of gyro when being about 1.4: 1.
The whipping of gyro 10 and operation are as illustrated in Figures 5 and 6.After cotton rope 26 was wound onto groove 14, as shown in Figure 5, gyro 10 can be by people's hand grip, and people's wrist is inserted in the circle ring 68 of cotton rope simultaneously.At this moment gyro 10 can be discharged or throw downwards, and the free end of cotton rope 26 remains on people's wrist place.When discharging or throwing downwards, cotton rope 26 will give gyro an angular speed from the expansion action of groove 14.When gyro arrived its surface that rotates such as floor, platform or desktop etc. in the above, cotton rope 26 should be launched fully.Along with cotton rope 26 is launched fully, gyro rotates on a surface of revolution 32, can pull at or guide cotton rope to move or guide gyro towards desirable any direction.People can utilize gyro to play, and for example, than the longest rotational time, move the most precipitous inclined-plane, surmount obstacles, race and fight, and for example, use weapon 34 to remove to attack adversary's gyro, and it is fallen down.
More than invention has been described and illustrate by preferred embodiment; under the situation that does not break away from design of the present invention and protection domain; also can make many conspicuous to one skilled in the art variations and modification; the present invention is not limited to the fine detail of said method or structure, because such variation and modification all will fall within the protection domain of claim of the present invention.
