  • About the DepartmentThe Department of Mechanical Engineering started in the year 1979, has nowgrown into a full-fledged Department offering undergraduate and PostGraduate courses in Mechanical Engineering with the present intake of 120students. The Department also offers two Post Graduate courses, M.Tech. inDesign Engineering and M.Tech. in Computer Integrated Manufacturing. Therehas been a significant improvement in quality, stature, infrastructure and otherfacilities.The department is a recognized Research Centre under VTU and 8 researchscholars are working for their Doctoral research. The department has to itscredit many funded projects from leading organisation like AICTE, NavalResearch Board, Institution of Engineers, etc.The department has so far graduated more than 4200 Mechanical Engineerswho are contributing significantly to the development and running of variouspublic and private organizations in India and abroad in the fields of Academics,Research, Industrial and Social sector.The Department of Mechanical Engineering is Accredited for 5 years byNational Board of Accreditation (NBA), New Delhi. ii
  • Message Dr. C. P. S. Prakash Professor and Head Department of Mechanical EngineeringIt is a matter of Pride that we are bringing out Department Newsletter “YANTRA20XI”AUTUMN ISSUE. I heartily congratulate the student editorial team for all the effort.The department is embarking upon lot of new Initiatives to reach a mark of AcademicExcellence.There has been a total turn around in the department, with lot of new academic initiativesbeing launched.

In most of the TechnicalUniversities its 2 years and in School of AppliedStudies mostly it is 1 and half years.Entry requirements for higher educationin Germany: Applying for any course in a GermanUniversity is very straight forward and hassle free.All international students applying for Englishtaught Master’s course in German universities isrequired to prove their English language capability,with a good TOEFL or IELTS score. Although, thecourses are offered completely in English, itshighly advised for students to learn German up tointermediate proficiency in both speaking andwriting, which will help students socialize andmore importantly increase their prospects insearch of Projects and Jobs. GRE is not mandatoryfor most of the universities, but considering theincrease in competition it could well decide yourfate. Any paper presentations or involvement insome research activities could boost your profile.So, all my fellow juniors at DSCE, I would like towish you all a great fun and success during yourbachelors and also for your future prospects. Withmy above article I have tried to share someinformation about higher education in Germany,which I hope would be useful for all those whowish to study further in Germany. If any of youwant to get more information on the same youcould contact me any time and I would be morethan pleased to help you out.I would like to thank Prof. Dr.C.P.S Prakash forproviding me an opportunity to share my thoughtsabout higher education in Germany.Wish you all success.

The principalconsideration for F1 designers is acceleration, andnot simply top speed. Acceleration is not justlinear forward acceleration, but three types ofacceleration can be considered for an F1 cars, andall cars in general, performanceAccelerationThe 2006 F1 cars have a power-to-weight ratio of1,250 hp/t Theoretically this would allow the carto reach 100 km/h (60 mph) in less than 1 second.However the massive power cannot be convertedto motion at low speeds due to traction loss andthe usual figure is 2 seconds to reach 100 km/h(60 mph). After about 130 km/h (80 mph) tractionloss is minimal due to the combined effect of thecar moving faster and the down force, hence thecar continues accelerating at a very high rate.
