    First of all, I would like to congratulate to all engineering students who made this choice for this excellent but tough career. You will meet lot of challenges on your way up. Be prepared to learn lessons everyday without any regret. Life itself is a teacher who teaches everyone everyday. For readymade experience learn from experienced people without any EGO. Few readymade points are: Being Engineer!! I have met many people who underestimate an engineer. They should know that Engineer cannot be judged by his grades or the views his HOD have for him. There are many qualities that engineer posses but might not found in his CV. Below are few of those qualities that give the engineer an extra edge. Career Scope- An engineer can become the software developer, bank manager, IAS officer, Business manager or even a BPO assistant. Values- There won't be anything called "Hot chick" in engineering college hence they understand their value and start respecting every girl. Working under pressure- Even though he (might have) never experienced "one night stand" ever but he knows how to survive examinations via "one night studies" Determination- Engineers love to sleep, but they never go to bed early. Nights are not made to be spent sleeping, the lecture is. Meticulous- Engineers are not lazy they are just highly motivated to procrastinate. Kindness- Engineers love everybody, apart from their faculty, project head, Deans, scientists, the new boyfriend of their ex-girlfriends, authors of their curriculum books, power cutoffs and slow internet. Team Work- Team Projects and group seminars might have failed to teach them this quality but mass-bunks and proxy attendance will surely teach the value of teamwork. Maturity- Engineers get to know that world is full of dishonest people when they join the college just because they have read the words like lavishing infrastructure, supporting faculty, 100% placements in their college brochures. Also when they get to know that girl's photo they saw on brochure doesn't exist. Network and relations- None of the relatives or any friend's mom ask them before but once they graduate everyone calls them at their home (so that they can fix their table fans, mixers or radio transistors). They recognize people with the mobile phone they carry and their laptop configurations rather than their names or faces. Fast learning- Even highly qualified faculty might have failed in teaching them a topic, but he will remember every word of it when his friend dictates it before entering the examination hall. Learn by Fun- Playing tic tac toe during class, late night counter strike tournaments, watching T20 with friends and completing Angry birds stages during lab sessions gave engineers more competence than any other sport. Sacrifice- Two engineers saw a hot chick in the mall, first reaction: ABE dekh be, Gazab !! second reaction: Jaane de yaar aukat ke bahar hai. Engineers also sacrifice their clean shaved look, to look more hard-working during exams for self-motivation. Resource management- Engineers know that a 3G connection and 4Gb pen drive is the first requirement before preparing for practical exams. Engineers know the value of every single bar in Wifi connectivity symbol and phone batteries. Staying Healthy- Engineers never compromise with their health, they stay fit and immune due to a regular dosage of Maggi and backed-samosa. Having food at Punjabi Dhaba and tea at extra-(un)hygienic Gumti is the part of their diet. Engineering is not just a degree... it teaches you the way of living life like a warrior. Engineering gives a perception and attitude. It teaches you the survival.

    Have u ever thought ,if a true mechanical engineer will write a love letter 2 his girlfriend....it would be somewhat like this....  My perpetual darling From the day u entered in the control volume of my mind my heart has become a closed system and its entropy is increasing according to III'rd law of loveodynamics....... The events and activities are so complex that i cannot find the optimum path after n nos. of iterations...... My heart is unable to sustain the cyclic load of ur frequent smiles and is near to endurance limit failure..... I am quenched in ur thoughts and no heat treatment can save my heart from decrystalisation now........ please do not test the bearing capacity of my heart valves and lower your yield strength......... please do not increase the compression ratio of my heart so much bcoz it is not designed to bear so much thermal stress..... please lower the octane no of ur temper as my little heart is not accustomed to so much undesired Knocking....... I am sure that u also would be experiencing some residual stress, and will someday show a proportionate straining of ur heart according to hooks law .........and as a Mechi i firmly believe in this theory.....so i will wait ....... till my little heart crosses its ultimate tensile stress and fractures Your LoveStrain-Hardened lover

    Hey there its my first blog hope you guys will enjoy it. First of all what is suspension..?? Its a basic unit which connects a vehicle to its wheel and provides a relative motion between them. It can be springs, dampers, struts, shock absorbers etc. In this blog I am gonna talk about basics of suspension. The first question is why do we need suspension..?? The basic need of suspension is to satisfy three basic needs which I call the three C namely comfort, control, contact.(I have copied it) We need to be comfortable while driving. Suppose there are stones or pebbles or other things on the road that can cause serious bumping of your vehicles so this makes driving uncomfy. The second and most important thing is contact. While driving tires need to be in contact with the ground or it ​can be hell of a dangerous. The third and most important thing which comes with contact is the control. Now the basic suspension is a spring. Its very simple it just stores energy and releases and are very common with independent suspension. The springs which we use in suspension are either coil spring which we use in independent suspension. The second type of spring is the leaf spring which we can see in trucks. What spring does that it stores energy from the motion of the force pushing into it when compressed and releases when it expands. The drawback is that it will bounce back your car every time the energy releases. So it does not find much use accept in solid wheel axle. The second type which we are gonna discuss are the dampers. Dampers consist of a cylinder with piston fitted into it. Piston has small holes and the cylinder is filled with oil. It basically converts the kinetic energy of shock into other form of energy generally the heat energy. The good thing about dampers is that it reacts to velocity which means that if there is a smaller bump it will dampen less and when the jerk is very large it will dampen​ more. Moreover it shows reactions to turning, braking and accelerations also. Now the main and most used component that's struts. It is a combo of spring and a damper. You know what's the best thing about struts it doesn't only act as a suspension it also act as a basis structural component as it eliminates the need of upper control arm and ball joint(except for wishbone strut which has upper control arm). Now last but not the least the tire has also some spring and damping properties. Hope you guys have enjoyed reading this. Next time I will explain MacPherson struts Cheers Image courtesy- www.google.com

    Hi Everyone, Not my strongest topic but I do know the answer to this one. A Newtonian fluid's viscosity remains constant, no matter the amount of shear applied for a constant temperature. These fluids have a linear relationship between viscosity and shear stress. Non-Newtonian fluids are the opposite of Newtonian fluids. When shear is applied to non-Newtonian fluids, the viscosity of the fluid changes. This can be either Dilatant - viscosity is directly proportional, Psuedoplastic - viscosity is Inversely proportional, Rheopectic - viscosity is directly proportional over time or thixotropic - viscosity is inversely proportional over time. Why do you need to know the difference? It's important to fully understand the properties of the fluids you're transferring, mixing, or pumping, because viscosity plays a major role in sizing and selecting equipment. Understanding how it reacts to shear will help you properly size and select all the equipment it comes in contact with. I am a very busy person, so apologies in advance if it takes a few days to get back to anyone. Great topic OP. Very important knowledge to have.

    That is a GenSet, and it is at least as much mechanical as it is electrical. Almost 50 years ago, I worked for a company that put together such packages, IC engines with any sort of driven machine. Generators were the most common, but we also powered pumps, air compressors, fans, whatever. It was a great place to work, with lot of very real, very serious, engineering challenges! DrD

    Hello there! Since the 1990s, computer simulation has become the most important tool for developing and / or improving various equipment for more daring projects. Based on the Navier-Stokes formulation, turbulence flow models, finite volume method and others in the case of computational fluid dynamics (CFD) and finite element methodology in the case of structural analysis (FEA), both tools required an upward computational cost, considering Random Access Memory (RAM), Number of Processors and Parallel Processing, typical features of High Performance Computers (HPC). On the other hand, the validation of computational simulations in the comparison of experimental tests requires simple physical models. The industrial process requires complex physical models, where there is apparently no validation of CFD or FEA cases. This becomes a restriction. Given this situation, what can we do? Does anyone have a suggestion and / or comment to try a potential solution to this restriction? Feel free to comment.

    In liquids, viscosity depends on the strength of cohesive forces between fluid molecules; hence an increase in temperature results in a decrease cohesive forces and a decrease in viscosity. For gases, viscosity depends on the momentum exchange between layers of gas moving at different velocities. An increase in temperature provides an increase in molecular activity and an increase in viscosity.

    TDC is Top Dead Center BDC is Bottom Dead Center For an engine with no cylinder center line offset, the cylinder center line passes through the crank axis of rotation. When the piston is farthest away from the crank axis, this is the TDC condition. When then piston is closest to the crank axis, this is the BDC condition. The term "dead center" refers to the fact that pressure acting on the piston in a dead center position produces no torque on the crank and hence no ability to move a load. The term derives from the era of steam power when single cylinder engines were very common. DrD
