## HOLIDAYS AND PHYSICS @ Mt. ABU ##


##Second semester exams just over and it was the time for a nice outing.So me and my friends decided to go to Udaipur(Rajasthan,INDIA).After spending a couple of days there, we left for Mount. Abu(approx. 6000 feet above mean sea level).On reaching there,we experienced a perfect weather at Mt. abu(specially when you come from 40degree C  temp.).It was all in all a mix blend of culture.heritage and nature for us.We didnt noticed how two days passed by. So on third day we decided to return to udaipur.On our journey back to udaipur we have to travel down 22kms of steep slopes of Mt abu.And since we were travelling in  a government bus ,the driver was driving very rashly although he seemed pretty experienced.He turned blindly on the brisk turns of Mt.I still remember we suddenly encountered a bus infront of us after a sharp turn.That journey was a real close shave for all three of us.


After reaching safely to udaipur i thought,that the boundries along that roadside was hardly half a  feet long which is sufficient to encourage toppling of any bus at greater speeds.So to prevent such accidental and fatal topplings on turns(~10m radii) i underwent some calculations.The result I  calculated was for minimum/threshold height of such boundaries.

OBJECTIVE--To calculate minimum height of boundaries of roads on hilly terrains.
Various dimensions are as follows-
1.Mass of bus ~ 10000kgs(average passenger bus of 84 capacity)
2.Speed of bus ~ 60kmph(16.6mps)
3.Track length of bus(distance between two rear wheels) ~ 2.6m
4.Average coefficient of  kinetic friction between road and tyre ~ 0.8
5.Radii of curvature/turn ~ 10m
6.Height of bus ~ 10 feet

Calculations-
Just balancing torques which are applied on bus when get accidently in contact with boundaries.
CENTRIFUGAL FORCE APPLIED ON BUS(F) = mv^2/r
                                                                              = 10000*16.6*16.6/10
                                                                              = 275560 Newtons
FRICTIONAL FORCE ON ONE TYRE(REAR) = coefficient of friction*mass of bus*acceleration due to gravity
                                                                             = 0.8*10000*9.81
                                                                            = 78480 Newtons
WEIGHT OF BUS                                              = mass of bus*acc due to gravity
                                                                            = 10000*9.81
                                                                           = 98100 Newton
Torque equations----
===> (1.5-H)*F-f*H-W*D/2=0
So after putting above values we will obtain a quadratic equation as follows
===>  78480 H^2 - 413340 H^1 + 127530 = 0
SO, the final value of H after solving above equation is
===> H= 0.33 metres/ 1.08 feets

SO THE ABOVE CALCULATED IS THE THRESHOLD HEIGHT THAT I THINK IS REQUIRED FOR PREVENTING ANY SORTS OF ACCIDENTS ESPECIALLY AT HILLY TERRAINS.

LAW OF CONVERGENCE(L.O.C)

Hey buddies,
I am back!! these university exams really sucks... duh..whateva i'll not take much of your valuable time and will take off with my new post.
One fine day,just running through T.V channels ,i stopped on to one of the channels displaying SHARE MKT....
It showed various crest and trough in terms of profits and loss.I murmured myself "what is that bullshit?...why people invest in share market even if they know that there are much more chances of a loss rather than gain//"
I gave a thought on it and asked myself...."Is it possible to cut down the chances of a possible loss dramatically??...if so how can we?""
I wondered "is it possible to do it mathematically?.....and BINGO!! a new idea landed on my top floor"
The most tricky part(as always) is the nomenclature of the theory.So by observing  the diagrams and calculations involved,i thought of giving it a name as"LAW OF CONVERGENCE (L.O.C)".Sounds cool right?? :P
BASIC PRINCIPLE INVOLVED-
This theory/law simply deals with the predictions relating to the gain or loss in share mkt.(as there can't be any accurate predictions in it)
The figure displayed below shows us a RED box with a pair of inclined lines.
For minimizing any sort of losses our basic aim is to pass the red boxes through the space provided between the inclined lines.(sounds crazy isn't it!!?? ;))...For now this much info. as i think is enough for today !..The later half of this post , which explains its working , its practical applications , and its use for minimizing losses will be covered in my next post.
Till then.....keep guessing///
as is it well said"One who uses his/her brains daily....lives a good long life"... ;)
