  • 2.   About the department The Department of Mechanical Engineering was started in the year 1979with an intake of 90 students. Over the years it has grown into a full-fledgedDepartment offering undergraduate and Post Graduate courses in MechanicalEngineering with the present intake of 120 students there has been significantimprovement in quality, stature, infrastructure and other facilities. It has so far graduated more than 4000 Mechanical Engineers who arecontributing significantly to the development and running of various public andprivate organizations in India and abroad in the fields of Academics, Research,Industrial and Social sector. The Department of Mechanical Engineering alsooffers two PG courses in ‘Design Engineering’ and ‘Computer Integratedmanufacturing’. The Department of Mechanical Engineering is Accredited by NationalBoard of Accreditation (NBA), New Delhi, and is ISO 9001 certifiedInstitution.     
  • 3.  Message Dr CPS Prakash Professor and Head Mechanical Department It is a matter of Pride that we are bringing out Department Newsletter“YANTRA 20XI”. I heartily congratulate the student editorial team for all theeffort. The department is embarking upon lot of new Initiatives to reach a markof Academic Excellence. I am happy to share that Mr Yash Parikh of MTech(CIM) has secured First Rank and Gold Medal from VTU in this year’sConvocation. There had been a total turn around in the students attitude whichhas given rise to some interesting projects done this year, I wish this trend willonly develop to make our department one of the best in the country.

  • 6.  Excerpts from interaction session of Editorial committee with Dr U Chandrasekhar,Additional Director, GTRE Bengaluru. The interaction was based on “Research- A Careeropportunity for Young Engineers”.Ed: Where can a young aspirant look to build his/her Research Career?  Dr UC: Research as the career option is available for engineers at various organizations likeISRO, DRDO, CSIR labs, BARC etc and also with many global players like GE, GM, Bosch,Daimler Chrysler etc., have setting up their R&D centers in India, the research options are ona growth path. So the numbers are continuously growing for Indian engineers.Ed: Can you list few major research projects presently being carried out in India.Dr UC: India is home for many major research works, to list I can say, • Satellite based communication and navigation systems for rural connectivity, security needs and mobile services. • Development of Heavy lift launcher • Reusable Launch Vehicles - Technology demonstrator missions leading to Two Stage To Orbit (TSTO) • Human Space Flight • Chandrayaan-2  Ed: Large number of students community doesn’t see Research as a career. What do you liketo say to them?Dr UC: Currently many engineers have started looking at R&D as a very important option.Many engineers from IITs are also joining. One example is recently department of spaceconducted entrance examination for their BE program (Trivandrum - IIST) and I understandlakhs of students wrote this examination.Ed: Freshers say “We dont find the growth in Research so fascinating as we get to experience in a Private or a MNC firm"Dr UC:This thinking is no longer valid - it has changed with global careers in R&DEd:Students in campus/ fresher feel "pace of work at Research" is a factor of concern for them to choose this field.Dr UC: Pace of work, excitement, sense of achievement in R&D labs are also veryprominent.Ed:What qualities should an engineer possess to build his/her career in the field of Research?Dr UC: Passion for research and commitment to cause.Ed: Piece of advice to students.Dr UC: If you are serious about R&D, please derive inspiration from great sons ofsoil like Dr. APJ Abdul Kalam, Dr, Vikram Sarabhai, Dr. Homi Bhabha, Dr. C V Raman, andyou can enable world-class achievements that can impact the lives of the people from allwalks of life.  4

  • 27.   Motivational StoryBoy was born to a couple after eleven years of marriage.They were a Loving couple and the boy was the gem of their eyes.When the boy was around two years old, one morning the husband saw amedicine bottle Open.He was late for office so he asked his wife to cap the bottle and keep it inthe cupboard. His wife, preoccupied in the kitchen totally forgot thematter.The boy saw the bottle and playfully went to the bottle fascinated by itscolour and drank it all.It happened to be a poisonous medicine Meant for adults in small dosages.When the child collapsed the mother hurried him to the hospital, where he died. The motherwas stunned. She was terrified how to face her husband.When the distraught father came to the hospital and saw the dead child,He looked at his wife and uttered “I am with you"The husbands totally unexpected reaction is a proactive behavior.The Child is dead. He can never be brought back to life.There is no point in finding fault with the mother. Besides, if only he hadtaken time to keep the bottle away, this would not have happened.No one is to be blamed. She had also lost her only child. What she needed at that moment wasconsolation and sympathy from the husband. That is what he gave her.If everyone can look at life with this kind of perspective, there would be much fewer problemsin the world. "A journey of a thousand miles Begins with a single step." Take off all your envies,jealousies, Unforgiveness, selfishness, and fears. And you will find things are actually not asdifficult as you think.MORAL OF THE STORYSometimes we spend time in asking who is responsible or whom to blame,Whether in a relationship, in a job or with the people we know. By this Way we miss out somewarmth in human relationship. Prof. Yash. B. Parikh Alumni , DSCE Mech (Rank holder and Gold medal Winner MTech CIM 2008-10) 25

St. Peter said to him, “Now Bill, you have done some good things and you done some bad things.

So he said St. Peter that he would like to go to hell. About a week later St. Peter Saw him being whipped by the demons And then he asked St. Peter ‘ What happened to all the beautiful women and the Beaches…. St. Peter replied, “That was just the screen saver”  Make a Difference:I awoke early, as I often did, just before sunrise to walk by the oceans edge and greet the newday. As I moved through the misty dawn, I focused on a faint, far away motion. I saw a youth,bending and reaching and flailing arms, dancing on the beach, no doubt in celebration of theperfect day soon to begin.As I approached, I sadly realized that the youth was not dancing to the bay, but rather bendingto sift through the debris left by the nights tide, stopping now and then to pick up a starfishand then standing, to heave it back into the sea. I asked the youth the purpose of the effort."The tide has washed the starfish onto the beach and they cannot return to the sea bythemselves," the youth replied. "When the sun rises, they will die, unless I throw them back tothe sea."As the youth explained, I surveyed the vast expanse of beach, stretching in both directionsbeyond my sight. Starfish littered the shore in numbers beyond calculation. The hopelessness ofthe youths plan became clear to me and I countered, "But there are more starfish on thisbeach than you can ever save before the sun is up. Surely you cannot expect to make adifference."The youth paused briefly to consider my words, bent to pick up a starfish and threw it as far aspossible. Turning to me he simply said, "It made a difference to that one."I left the boy and went home, deep in thought of what the boy had said. I returned to thebeach and spent the rest of the day helping the boy throw starfish in to the sea. Based on the story by Loren Eisley Puneeth 6th BE 26  
  • 29.   Musings of a Confused Engineering Mind “Should I wear this red tie or should I pick up the maroon one instead for today’s meeting withmy client?”...”Should I laze around in the house for the weekend or just chill out with my friends at the discotheque?” I believe each one of us at some point of the day go through a similar phase of indecisiveness. Any guesses? The word is “Confusion”. Yes, it is this confusion that rules the world and beyond.Till date even the top notch scientists are speculative over the origin of the universe and space- time and hence they had to seek refuge into a number of theories such as the Big-Bang Theory, the String-Theory among others. But this doesn’t end confusion from their minds for they are constantly at work to find a full-proof theory that would describe every property andcharacteristics of the universe and answer the myriad questions hurled by the critics out there. Now that was about the scientific world where confusion reigns supreme. Now coming to our practical world, confusion plays no lesser part in almost every aspect of our lives. Very few smart and able men can keep confusion at bay. The remaining are confused right from dawn to dusk. I belong to the latter category. About me, I was as much confused in childhood as I am now. Confusion seems to be synonymous with my name. Confused? Let me clarify. My name is an amalgamation of a complex set of unpronounceable syllables as a result of which often people find it difficult to pronounce my name and as a result end up spelling it wrongly. No doubt most of my marks card bare the same name but with different spellings. My fate!Another trait of my eternal confusion is that it was only when I was in the seventh grade that I came to distinguish between the left and right sides over which I get confused sometimes even now. Moreover, after being confused for all these years I can say that I’ve attained some sort of mastery over this special trait possessed by me. My confused state of mind can be divided into three categories. The first one is that I am a person who is scientifically confused. No doubt I nursed a personal grudge against Newton when I was in school. As a result I ended up messing my grades quite often in school which was followed by a letter to my parents from the principal. But interestingly or rather confusingly the letter never found its way to my home. However, I am proud to belong to this class of scientifically confused people because I personally believe that all great scientists were a confused lot and in the process of removing their confusion they ended up discovering or inventing something extraordinarily great. Now I am not saying that I am great for I have my confusions over that as well! Secondly, I’m a person who is spiritually confused. I am confused for that matter because if God is one and all religions preach the same tenets of finding God, then how come so much hatred and sin in the name of religion all over the world. All these make me all the more confused. Lastly, I am a person who is simply confused. I sometimes wonder had there been some sort of Confusion Quotient (CQ) to measure the degree of confusion of the mind, I am sure I would have had a high CQ level. None of my tasks are completed without the timely intervention of confusion. But I must say that I am proud to possess such a powerful quality for with the help of this special trait many minds have produced many things unheard of before. So why can’t I?With this bit of solace I continue my journey hand in hand with this faithful companion for many more confusing days to come in future...  - Tridib Das, BE6th Semester 27
