CRICKET MY FIRST LOVE

CRICKET MY FIRST LOVE

Well hello everyone once again , this time it’s not about my photography or physics or anything, but this time round I would like to share my experience with the sport named “CRICKET”.
I still remember when I was around 6 years old  I got my first cricket bat. It was actually a “mogri” one which is used by Indians to wash clothes  :P but nonetheless it was precious for me .I used to play with my father and surprisingly my dog too! Let me tell you my dog  was splendid  during fielding.
I am not sharing this to show what trophies or tournaments I have won, in fact I have won none . But its my unbiased love towards the game that I am writing .And by reading this any sport lover could relate yourselves quite easily.
Being an Indian fan, I was a die hard fan of SRT(Sachin ramesh tendulkar), I wrote “was” because he retired from the game for almost 6 months now. I still remember it was the World cup of 2003 when I first got to know how exciting the game can be. In that W.C few things happened like I got the know about the rules of the game coz earlier I used to take my bat back once I got out ,later realizing it was not allowed :P . Even under the guidance of my grandpa and dad I learned to see the score of the undergoing match and infinite etc!
Sadly India lost to Australia in the finals but it was enough for “cricketing passion” to reach its peak.
During that world cup 2 aussie players became my idols namely, Glenn McGrath and Brett Lee (both bowlers by the way).Their deliveries were so fast and accurate that any reckless shot by the batsman was finally turned out to be a wicket. So I thoroughly enjoyed bowling from my 6th grade onwards!!
There was a inter-class match where I took 4 wickets in an over , and I’ll brag that no matter  what. :D
During that time our house shifted , landing me in the locality of cricketing buffs! They were guys of my age (10-15 yrs).We used to play every weekend and don’t ask what used to happen during vacations?!


I’ll tell you the schedule
·         Waking up – 6:00 AM
·         Getting to the field –6:30 AM
·         Warm ups – half hour (god knows what warm up exercises we did :P but still…)
·         Session 1 of play – 7:00AM – 12PM
·         HOME (scolding time/MOM) – 12PM – 1PM
·         TV(Old cricket matches if no lives going on) – 1PM – 2:30 PM
·         Scolding time/dad – 2:30PM – 3:30PM
·         Escaping to the field (once parents fell for afternoon nap) – 4:00 pm
·         Session 2 of play – 4:30 PM – 7:30 PM
#period
In those days for after any good results or birthdays I demanded on cricketing stuffs!
Ranging from 4bats,2leather balls, gloves, pads ,helmet to lower abdomen guard ( I still don’t remember I’ve ever used it).
One day during my exams my father dragged me to the home from the field because of bunking studies.
That incident deepened my love towards it( it got nearly 90% that year :P ).

So this happened for like 5-6 years until I came to 11th grade .I was sent to other town for studies .That time I was undesirably kept out of the game .Let it be not watching a match due to lack of entertainment or not playing a match for almost 2.5 years I felt terrible. Even when I wanted to no one did(geeks!).But every time shall pass. I finally got into a prestigious university with good grades ( still wondering how..) and got back to the game with 200% energy.
Playing whenever getting time between lectures and sharpening bowling skills are a part of my daily schedule. And let me tell you can’t face my bowling that easily ;) even though my idols got retired my passion hasn’t.
I am in third year now and loving the game like never before especially after India wining the 2011 WORLD CUP almost after 28 years.!!!
#CHEERS TO ALL CRICKET LOVERS LIKE ME!

DUST COLLECTOR

Introduction – Once the full welding of coils are done, they are subjected to various tests which ensures that following operations namely projection welding, bending and full welding are performed accurately and the coil will then be sent for Radiography testing.
These tests includes:
·         Ball test.
·         Hydraulic test.
In ball test,a metallic ball of diameter same as that of internal diameter of the coil’s pipe is passed via pneumatic process i.e. passing compressed air through the pipe. This process ensures that the bends are perfect.

But it has been observed that huge amounts of dust get generated from the pipes. To eradicate the above mentioned problem we developed a device and named it as DUST COLLECTOR.

MANUFACTURING FLOW PROCESS –

We started with searching used metallic cans which are being used for painting coil modules. So after finding them we cleaned them with the help of thinner for removing inner solidified paint. After that our next aim was obtaining PVC(polyvinyl chloride) pipes and an accurate hole(diameter same as that of pvc pipe) was made on the lid of the can. Now one end of pvc pipe was inserted into the can(which is filled with water) and other end is fitted to a piece of pipe. Now the successive end of m/s pipe was calibrated with a butt joint clamp. The clamp acts as a junction between the dust collector and the coil.
Now for pipes/coils of different diameter we use butt-joint clamps of same diameters as well. Now when the compressed air is passed , the dust gets collected into the dust collector and we must ensure that the lid of the can is perfectly sealed which inturn prevent sudden splash of water coming out of the water filled can.

FURTHER MODIFICATIONS-

Since the container in dust collector is completely sealed, passage of high pressure compressed air can act as a potential threat because the pressure is around 10 bar. To nullify the threat we provided a vent in the form of of a bent tube welded and attached at the top of the collector .This tube is TIG welded with high precision on the lid.

Projection Welding using xpandrel technique

Hey guys, its been a couple of months i have written a blog since i was busy with semester exams and nowadays industrial training of 6 long months.
So this present post is on the revolutionary technique of attaching fins on the tubes of various diameters without using resistance spot welding rather making the use of XPANDREL Technique.
Let me give you a basic idea of what it is? Actually what we are going to do is,we'll use a mandrel and by inserting it in the tube(generally mild steel) it will expand and due to that the fins will get fused on the periphery of the tubes!!!

Further calculations and observatory results in the next post,till then keep guessing! ;)

## 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.
