Beauty of Mechanical Engineering

-
Mechanical Engineering is a beautiful branch of engineering. It’s been here since ages. It includes study & application of principles of mechanics, energy & fluid mechanics to create mechanical systems aimed at doing innumerable tasks. As a course of study, it begins with learning fundamentals of statics & dynamics which forms the base. Along with it comes Thermodynamics which is again a fundamental subject which deals with study of heat, work and energy in the form of First, Second and Third laws. It also includes study of Availability & Irreversibility, Entropy, Real Gases, Thermodynamic cycles, Properties of Pure Substances like steam. All Thermal Power Plants work on principles of Rankine power cycle. This forms the basis of all Thermal Energy Systems. Fluid Mechanics is another subject which is taught with an objective to understand properties of various engineering fluids along with application of principles of statics & dynamics. In the first phase w...

NanoComposites in Tennis Balls

-
Nano composites consists of nano sized particles embedded in some type of matrix -are group of promising new materials being infused in some of our modern technologies.  One type of nano composites is currently being used in high performance tennis balls. These balls retain their original pressure and bounce twice as long as conventional ones. Air permeation through walls is inhibited by a factor of two due to presence of a flexible and very thin (10 to 50 microns) nanocomposite barrier coating that covers the inner core. This nanocomposite coating consists of matrix of butyl rubber, within which is embedded thin platelets of vermiculite, a natural clay mineral. The vermiculite platelets exists as single molecule thin sheets- on the order of nano meter thick-that have a very high aspect ratio.  Furthermore vermiculite platelets are exfoliated that is they remain separated from each other. Also within the butyl rubber, the vermiculite platelets are aligned such th...

Campus placement -Mad Rush

-
In some of my previous blogs, I had mentioned about not getting selected in Tata motors. I can recall that moment I realized this I lost my sense for a while.  I couldnot stop being extremely sad. My friends-Jayant(J)& Ajay(A)  supported me (I) & Madan(M). Out of V4, only A & J were through and I & M were still jobless ! We were group of 4 incidently top 4 of the Institute ! I can recall J literally asking me to forget eveything ,even the fact that A & him are got selected. A added that you & M are surely going to get selected in the next company -that was TCS ! I can recollect dialogue from movie 3 Idiots on human psychology which is apt here - " jab dost first aata hain toa jyada dukh hota hain". "Job-Full" guys promised not to have any celebrations unless rest 2 get through. I & M started preparing. TCS was all about Vocab and simple Maths. We were comfortable with that. Actually we were not comfortable with the compu...
