If u want to save your future save girls
=> read this poem below to heart touching !!! Share it as much as u can
आप सभी से ये गूजारीस है एक बार जरूर पडे
कोर्ट में एक अजीब मुकदमा आया
एक सिपाही एक कुत्ते को बांध कर लाया
सिपाही ने जब कटघरे में आकर कुत्ता खोला
कुत्ता रहा चुपचाप, मुँह से कुछ ना बोला..!
नुकीले दांतों में कुछ खून-सा नज़र आ रहा था
चुपचाप था कुत्ता, किसी से ना नजर मिला रहा था
फिर हुआ खड़ा एक वकील ,देने लगा दलील
बोला, इस जालिम के कर्मों से यहाँ मची तबाही है
इसके कामों को देख कर इन्सानियत घबराई है
ये क्रूर है, निर्दयी है, इसने तबाही मचाई है
दो दिन पहले जन्मी एक कन्या, अपने दाँतों से खाई है
अब ना देखो किसी की बाट
आदेश करके उतारो इसे मौत के घाट
जज की आँख हो गयी लाल
तूने क्यूँ खाई कन्या, जल्दी बोल डाल
तुझे बोलने का मौका नहीं देना चाहता
लेकिन मजबूरी है, अब तक तो तू फांसी पर लटका पाता
जज साहब, इसे जिन्दा मत रहने दो
कुत्ते का वकील बोला, लेकिन इसे कुछ कहने तो दो
फिर कुत्ते ने मुंह खोला ,और धीरे से बोला
हाँ, मैंने वो लड़की खायी है
अपनी कुत्तानियत निभाई है
कुत्ते का धर्म है ना दया दिखाना
माँस चाहे किसी का हो, देखते ही खा जाना
पर मैं दया-धर्म से दूर नही
खाई तो है, पर मेरा कसूर नही
मुझे याद है, जब वो लड़की छोरी कूड़े के ढेर में पाई थी
और कोई नही, उसकी माँ ही उसे फेंकने आई थी
जब मैं उस कन्या के गया पास
उसकी आँखों में देखा भोला विश्वास
जब वो मेरी जीभ देख कर मुस्काई थी
कुत्ता हूँ, पर उसने मेरे अन्दर इन्सानियत जगाई थी
मैंने सूंघ कर उसके कपड़े, वो घर खोजा था
जहाँ माँ उसकी थी, और बापू भी सोया था
मैंने भू-भू करके उसकी माँ जगाई
पूछा तू क्यों उस कन्या को फेंक कर आई
चल मेरे साथ, उसे लेकर आ
भूखी है वो, उसे अपना दूध पिला
माँ सुनते ही रोने लगी
अपने दुख सुनाने लगी
बोली, कैसे लाऊँ अपने कलेजे के टुकड़े को
तू सुन, तुझे बताती हूँ अपने दिल के दुखड़े को
मेरी सासू मारती है तानों की मार
मुझे ही पीटता है, मेरा भतार
बोलता है लङ़का पैदा कर हर बार
लङ़की पैदा करने की है सख्त मनाही
कहना है उनका कि कैसे जायेंगी ये सारी ब्याही
वंश की तो तूने काट दी बेल
जा खत्म कर दे इसका खेल
माँ हूँ, लेकिन थी मेरी लाचारी
इसलिए फेंक आई, अपनी बिटिया प्यारी
कुत्ते का गला भर गया
लेकिन बयान वो पूरे बोल गया....!
बोला, मैं फिर उल्टा आ गया
दिमाग पर मेरे धुआं सा छा गया
वो लड़की अपना, अंगूठा चूस रही थी
मुझे देखते ही हंसी, जैसे मेरी बाट में जग रही थी
कलेजे पर मैंने भी रख लिया था पत्थर
फिर भी काँप रहा था मैं थर-थर
मैं बोला, अरी बावली, जीकर क्या करेगी
यहाँ दूध नही, हर जगह तेरे लिए जहर है, पीकर क्या करेगी
हम कुत्तों को तो, करते हो बदनाम
परन्तु हमसे भी घिनौने, करते हो काम
जिन्दी लड़की को पेट में मरवाते हो
और खुद को इंसान कहलवाते हो
मेरे मन में, डर कर गयी उसकी मुस्कान
लेकिन मैंने इतना तो लिया था जान
जो समाज इससे नफरत करता है
कन्याहत्या जैसा घिनौना अपराध करता है
वहां से तो इसका जाना अच्छा
इसका तो मर जान अच्छा
तुम लटकाओ मुझे फांसी, चाहे मारो जूत्ते
लेकिन खोज के लाओ, पहले वो इन्सानी कुत्ते
लेकिन खोज के लाओ, पहले वो इन्सानी कुत्ते ..!! Please read and share.

U accept it or not but u should admit that in INDIA there is increasing in cases of child trafficking & rapes..
Here I m going to explain two stories for u guys relative to my title.. evalute them by yourself..
Story(1)
=> a girl named Nisha is doing job on call centre.. one day her colleague was on leave , so she needed to do her work as an overtime. It was quiet late when she finished her work and left office.. then she went to nearby taxi stand to take a ride for home and it was almost 12:30 AM.
=>. She was waiting for cab and a car came which was driving by a man..he offered her lift , but she refused ( man!! U can't just trust anyone). Suddenly that man came out of car and stood besides her ( trust me she was too much afraid due to this act ) but with her surpise, that man told " mam u r my responsibility and I will wait till u get proper ride.."
=>. After a while a taxi came and that girl left for home by taxi... But during her riding home she looks worrying for her safety when taxi driver saw that he told her " don't worry miss u r my responsibility & it is my duty to take u home safely".. and finally she reached home safely..
=> I can say that if at least two men show their goodwilling any women can reach their home without scratches..
Story(2)
=>. There is boy 6-7 years old , studying in a school.. one day after schooltime a man came to him and told " son, your mother is busy today. So she told me to pick u up after your schooltime." And man offered a chocolate to boy... Suddenly boy asked the man " uncle what is paassword ?".. the man hesitated to give answer . As soon as he hasitated boy ran in school campus and saved himself...
-> The boy did this bcz when he starts to go school her mother teached him one code word ( a password) and she told him that "this is a secret password between u and me. Don't ever tell anyone about it , if anyone except me come to pick u up from school ask him about password and if he can't tell u password then run in school campus and inform securities."
=> In every country child trafficking is major problem .. if u r a busy one and worrying about your children u should try this method..

What is intolarance?? Is India really intolerance or what??
This is defination u can find on google ' unwilling to accept someone's view , beliefs which differ from others'.....
No country in entire world can be intolerance . Only people and some certain organisations can be intolerance.
-> Nowadays some freaks spreading rumor that India is becoming intelorance country !!! ( really !!!) . I can't understand on what base they are willing to say something like this.. one dadri incident can't make entire country intolrance... I must say crowd responsible for that incident should be fram as intolerance... Just some idiotic politicians making small things bigger for their own benefits....
-> I was checking and fb page earlier and I found and awesome comment which says ' a man walking on road with waving his hand and shouting that I have freedom to do anything VCs its my constitutional right.. suddenly his hand hit on other's chick , but he didn't say Sry and countinuing his act... The other man hit him hard and said " your freedom ends at where my chick starts.". ..........'
-> India is bestest best country in entire world... I m and Indian Muslim and I don't need any proof which proves that I m patriot.. I m a Muslim and that's enough to prove that I m patriot... Islam teaches me that love your country morethan your lives... No one can be said a Muslim until he loves his country more than his life.. my religion gives me permission me to eat meat , but it doesn't tell me that I must eat it.... I will not eat beef if it hurt someone's feeling...u can't tell every Muslim terrorists bcz of some few ppl , like this u can't make entire country intolerant due to some brainwashed freaks ...
-> 3-4 days ago I read a news that 20-30 people of certain organization attacked on a certain religious place and they tore women's cloths and threw a 2 years old child... Now this is told intolerance!!!! What makes those people think they can do anything they want , and no one can stop them...????!!!!!!!???????. I don't know answer of this question but maybe among u someone knows , I m asking u do u know answer of this????

Gear drive
What is gear?
Gear can be defined as mechanical device which is used to transmit power from one shaft to other shaft at different r.p.m for short distance.( gear is a wheel with teeth )
Some will see it like that gears are only used to transit power for short distance so it should be its disadvantage. This people should consider example of watches.
Besides it gear can provide constant velocity ratio and it also transmit large power.
There are different types of gear drives which are used depends on axis of shaft and requirement of power at different r.p.m
Some disadvantages of gears are
1) expansive manufacturing process.
2) proper lubricants and proper method to apply it is needed to reduce noise and wear.
=» Types of gear are mostly depends on following factors :
-> Axis of shafts between which power is being transmitted.
-> Depends on type of teeth used.
-> Depends on peripheral velocity.
-> Types of gearing .
All types will be discussed briefly in next post
Thursday, 28 January 2016
Law of gearing ( in very simple words)
for Power transmission between two shafts there are mostly two type of mechanisms are used 1) chain or belt drive 2) gear drive..
But where constant velocity ratio is required and for power transmission for shorter distance gear drives are used.
Gear drives also helps to increase or decrease RPM of driven shaft..
Law of gearing ' WHEN TEETH OF TWO DIFFERENT GEARS ARE MESSING WITH EACH OTHER AT THAT TIME COMMON NORMAL OF ANY TWO MESSING TEETH MUST PASS THROUGH PITCH POINT.'
If common normal passes through pitch point then we can get constant velocity ratio.
=» Figure for law of gearing is as shown..
Formula for law of gearing is ( by figure)
w(2) / w (1) = O(2)P / O(1)P
FOR DERIVATION OF IT REFER TWO FORMULA SHOWN IN FIGURE.
LAW OF GEARING PROVES THAT GEAR DRIVE HAS CONSTANT VELOCITY RATIO.
