My Experiments with "Pambaram" - II

So, while the last post was the prologue to this one ,let me continue with my experiments.... :)

It went like this for two whole days....A bit comical Thou..but it meant serious business for two whole days. Tried my best and applied every bit of my effort..... All to make a Top Spin...
"Mastering the Art of Pambaram Vitting"

I even had a thought of calling up Vijayakanth for tips...But poor guy,he was in a political turmoil then. So yeah,well equipped with a string and the top i started to a vacant place in front of house where i could stealthily undergo the training.
Took tips from everyone and started to apply everything.But net result 0....

Hence i finally decided to resolve the issue applying my Engineering Skills. So sitting down,analysing the planetary data,Gravitational Pull and the earths motion into account ,considering the feedback,changing the angle of inclination etc etc....i started to analyse ,in what all ways i can "Master the Art of Pambaram Vitting"

hmmm....Not to forget how embarrassed i was when kids stared occasionally with a kind of mocking look...hmmm..."avanga Manasula enna Odithho" seeing a grown up guy like me..sitting with a top and the string.....

So here goes my application of physics....

"A rapidly spinning top will precess in a direction determined by the torque exerted by its weight. The precession angular velocity is inversely proportional to the spin angular velocity, so that the precession is faster and more pronounced as the top slows down.The direction of the precession torque can be visualized with the help of the right hand rule.This process involves a considerable number of physical and mathematical concepts. A torque is exerted about an axis through the top's supporting point by the weight of the top acting on its centre of mass with a lever arm with respect to that support point. Since torque is equal to the rate of change of angular momentum, this gives a way to relate the torque to the precession process.The expression for precession angular velocity is valid only under the conditions where the spin angular velocity w is much greater than the precession angular velocity wP. When the top slows down, the top begins to wobble, an indication that more complicated types of motion are coming into play."

While i was thinking so much but could'n finally make a top spin, even after working hard for two days,a girl(must be less than 8yrs) came over there,stared at me with a subtle smile,took a top from her pocket,spun it just like that,then took into her palm while it was still in motion with help of the string.Then oru nakkalaana look..Thats it...Then i decided...

" Ivalo Nadantha Apparamum unakku ithu venamannu "...... hmmm....

In mounam Paesiyathaey style... "Avala Vantha,Avala Nakkala Oru Look Vitta,Avala Pambaram Vitta,Avala kaila Edutha,Avala Siricha....hmmm"
