Experimental spin top height 11 cm height base base radius 2 cm 5.5 cm 5.5 cm
radius scan 4. Cm, weight 10 g with angular speed of 100 ma red/s all 100 times found that top has angular speed
precession 15.206 red/s
.By comparison, khamnuan from top shape resembles a large semi-circle with a radius of 3 cm
radial cylindrical. 0.4 cm 7 cm long, with the center of mass height from floor 3 cm rotation with angular speed 100
red/s finds that a top is precession angular speed calculated 17.161 red/s
.When comparing the two values have different values; Because the calculation has not yet calculated the force covers
.Friction resistance between the ground to the top, which is the angular speed of the top is fixed, and the trial is not yet able to control the value of angular speed of a top powerful constant. Therefore, the value that comes out, there are some discrepancies.
