Hello Folks!!!

As expected, consumermate.com is ready with their new category (categories! I guess!!). Firstly, I had seen consumermate in November 2009. Those times, it provided pretty nice tools and information about laptops and mobile phone handset. Soon later, they added LCD’s and Plasma TV. And now, they are ready with two more rocking products, Digital Cameras and Camcorders. At start of this article I have written “As Expected”! The reason is here. I frequently visit consumermate for latest tech products. I am monitoring that, these people have their unique concept, they have developed appropriate tools (like search and compare tools) and most important “They are constantly maintaining, updating and growing with pace!”

Searching your camera is very easy here. It’s similar to those tools Laptop search or mobile search. You can select cameras on cost and hardware basis, compare them and get complete information about products. Consumermate have new feature which lets you enter your product and contact information. Then dealers in your city will contact you.

Being related to Animation and Filmmaking field, I have used some high end cameras. Few days back, my friend purchased pretty expensive version of nikon camera. I asked him about high costs. But when I handled camera, saw its functionality and rocking outputs, I was damn amazed. It worths! I am currently using that SONY Cyber Shot and canon powershot digital camera. Canon powershot is cheaper but its performance overtakes other. Moreover, it have very simple interface so anyone can learn to use it very easily. The camera is so magnetic that sometimes I feel I am not using camera for taking photographs, but taking photographs for using the camera!

So, what yours choice Nikon or some canon slr type. Whatever! Go to consumermate.com. They know what you need to know! And by the way, after you get camera, I would like to see some photographs by you. So, don’t forget to post links to your photos below!

Till then, Have a nice time!!!

C. Most popular programming language. Everyone who knows programming, definitely, will be agree with the fact that first language to start programming must be C. There are  a lot of properties of C which trains newbie for upcoming advanced technologies. According to me, maximum people in programming field have learnt C and as there first language.

I am writing this for people new to C who are in search of some good books. Actually, there are tonnes of good books regarding C. But here I am talking about newcomer.

Recently I was learning C for C-DAC entrance exam. I have planned this article at that time only. So, when I looked around I was pretty confused to see so much books on C. Moreover, I am from Mechanical Engineering background which says that I know nothing about any book of C. Coming back to point, I talked with few of my friends, one is from Information Technology Engineering. He suggested me ANSI C written by E Balagurusamy which is published by Tata-McGraw Hill.

Leaving the story behind, I have learn C from the book. This is really a good book for C. I asked expert was good decision after-all! The book is definitely written for a person who know nothing about C. Book is given with some solved examples and many of the exercises at the end of each chapter. In short, when one studies this book thoroughly and seriously, at the end have good base of C programming. Along with book, online resource is provided for some reference.

ANSI C does not include one major part of C programming. That is Data Structures. Its not possible either to crunch it along with. So along with ANSI C, one must have a good book about Data Structures. A book written by Yashwant Kanetkar, ‘Data Structures Through C‘ can be good option for the same. It is published by BPB publications. This is core book for Data Structures. But this book is for medium to expert level programmers. Really hard for newbies. But if you have approached this book after completion of ANSI C, then its not that hard to grasp. Book provided the CD that contains codes, problems and animations which help to grasp the concepts.

So, till now we discussed 2 books on C. Now, I am going to recommend one more book, “The C Programming Language” by Dennis Ritchie and Brian Kerningham. This is 1st ever book on C written by creator of C. It is popularly known as “K & R C”.

I think this is a lot of stuff about C. These are must have books of C, obviously, according to me.

Finally, according to me, must have books for C programming are:

1. ANSI C by E Balagurusamy, Tata McGraw Hill.
2. C Programming Language By Brian Kerningham and Dennis Ritchie.
3. Data Structure Through C by Yashwant Kanetkar, BPB Publications.

Still, few more books you must look at are:

1. C: The Complete Reference, 4th Ed. by Herbert Schildt, McGraw Hill Publications.
2. Let Us C by Yashwant Kanetkar, BPB Publications.
3. Test Your C Skills by Yashwant Kanetkar, BPB Publications.

Hello Friends,

Today, I am going to give you a strategy to succeed in any exam around. You may be thinking that this is EngiBlogger- Engineering Blog, so nothing to do with non engineering people. Please wait. What I am going to discuss is not engineering exams but a thinking process that I learnt from marvels around and felt astounding. So, stick with me here.

Few days back, I was watching a Steve Jobs video on youtube. (I guess everybody knows Steve Jobs! For them who don’t know him, Steve Jobs is founder of great company like Apple, he is developer of Macintosh operating system and he is behind the great 3d Animation Studio PIXAR. Now please don’t tell me that you don’t know Apple, Macintosh and PIXAR!). In that video Steve told some of his life experiences. For me most important was one strategy he discussed. Definitely, it was’t how to make marks in exam.

Steve tells one story about death and also how close he was once. From that event Steve recognized one pattern.  Every morning he wakes up and asks a question, “What will I do if this is my last day on earth?” Whatever is the answer, that is most valuable thing to perform!

I figured out that this is a RULE. And RULES are timeless and remains unchanged in any situation or field. So, in context of exams, how can we apply this strategy?

Got the Answer! OR rather I must say Got that Question? Yep. When you are preparing for any exam, just ask yourself, What will I study if this is last day remained for my preparation? OR What will I study if tomorrow is exam day?

The answer you get by asking the question is definitely most important part to study. Now, you have to perform, means, really learn that part as if tomorrow is Armageddon (Exam!). Because,  mere this question is not enough! Next step is MOST important.

PERFORM!

There is reason behind the highlighting second step perform. Almost everyone knows what he/she should do? But they don’t. They just caught up and procrastinate. Its true, everybody procrastinates, I am sure I do. Just knowing how to solve problem is not enough. Action is of a lot importance. Otherwise somebody who don’t know what to do is better than else, who knows but don’t perform!

So, got the complete picture. Now, go wild, Win the Battle. And after battle, think of sharing this article or leave comment below!

Thanks for Reading!

According to syllabus of University of Pune, Applied Sciences II is studied in First Year of Mechanical Engineering. As its in 1st year, student are a lot from 12th standard thinking which obviously works with Applied Sciences. Like 12th it contains two subjects, Applied Physics and Applied Chemistry. Among them I was always fan of Applied Physics.

Applied Physics:

Applied physics is subdivided in some more parts. I have given possible explanation to each of them below.

Wave:

It covers two major parts, Wave Equation and Wave Particle Duality. Some terms are Heisenberg Uncertainty Principle, wave nature of matter, wave electron diffraction, Davission and Germer’s Experiments, concept of wave function and probability interpretation, tunneling effect etc.

Lasers:

This is really attractive parts and moreover those alien movies have so much popularized laser that we don’t need to tell about it. Here we learn how laser is generated and its vast applications today in various branches like Medical, Information Technology, communication system, fiber optic etc.

Semiconductor Physics and Modern Physics:

Huge revolution in electronics is output of semiconductor technology. Here we learn about semiconductor materials like beryllium, silicon etc. then terms like Hall effect, Fermi level, Fermi Dirac Probability etc. In modern physics we see electron level physics like electrostatic and magnetostatic focusing.

Applied Chemistry:

Again applied chemistry is subdivided into subtopics which are discussed in brief below and one more thing chemistry part of applied sciences II is easier than physics as compared to situation in applied sciences I:

Fuels:

It teaches us a lot about fuels. Basic distinction like Solid, liquid, gaseous then measuring the calorific value of fuel, bomb calorimeter, boye’s calorimeter etc. Various fuels we learn are coal, petroleum products like petrol, diesel etc. LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), LNG (Liquefied Natural Gas) rocket propellants etc.

Electrochemistry:

This is a lot about cells. From basic we learn things like EMF concept (Electro-Magnetic Force), redox (Reduction-Oxidation) reaction, Nernst Theory etc. After cells batteries approaches us. There are huge types among the batteries.

Analytical Chemistry:

After photochemistry we see, analytical one. We cover electromagnetic radiations, spectroscopy, ultraviolet visible spectroscopy, Infrared spectroscopy, atomic absorption spectroscopy, chromatography, gas chromatogrphy etc.

Corrosion:

Last part of chemistry. We start with simply types of corrosion, atmospheric corrosion, wet corrosion, then factors affecting, cathodic and anodic protection etc. and much more.

This is not complete overview of the Applied Science subject but still its good for 1st introduction with subject. That’s all.

Thanks for Reading.

So, we are now on Electrical Technology. According to syllabus of University of Pune, ET (Electrical Technology) is studied in the second year of Mechanical Engineering. By the way, this is totally Electrical Engineering subject. And almost similar subject is there for Electronics and Telecommunication Engineering. The part which is covered in ET is very important when seen from Mechanical Engineering aspect.

D.C.Generator and D.C.Motor:

As name suggests, this part covers D.C.Generator and is pretty easy. D.C.Generator and D.C.Motor are almost same in construction and there workings are just vice verse. D.C. generator takes shaft power in and gives output as electric power and oppositely, D.C. Motor takes electric power in and outputs the brake power on shaft.

Motors, Transformers and Alternators:

There are plenty of motor types and we need them in different applications. So, mere learning the D.C.Motor is not enough. We learn induction motors, special purpose motors like servo motor, stepper motor, synchronous motors etc. Also, we learn transformers and alternators.

Electrical Machine Selection Maintenance and Electrical Power Measurements:

The selection of perticular electrical machine is dependent on type of work to be done. Suppose, when we need to have very high torque from motor the obvious selection could be D.C. series motor. For robot arms, stepper motor or servo motor can be used.

Electrical Heating, Welding and Illumination:

These are most obvious uses on electric energy. Illumination is kind of theory part that covers some basic aspects about lighting or rather types of lighting and efficient lighting. Though easy, Illumination contains huge number of definitions.

So, this is brief of Electrical Technology.

Design of Machine Elements is generally referred as DOME. Wait! DOM and DOME both are names of different subjects in engineering. DOM is Dynamics of Machinery. So, moving up to DOME again. DOME is studied in Third year 1st semester of mechanical engineering according to university of Pune. As usual, subject is divided into 6 main parts called as units. Generally, each unit contain similar kind of matter but sometime its not possible.

Introduction:

We can’t say that first unit is simple and introduction but some part of this unit is introduction which makes student a bit ready for design subject. It covers requisites of design engineers. standards etc. After the introduction DOME covers some of the small design elements which are very common for mechanical engineering students. These parts include knuckle joint, lever, shaft design, cotter joint, curved shafts etc.

Shafts, Keys and Couplings Part:

This is second unit and as name suggests it covers various types of keys, shafts. Its somewhat difficult part just because of its vastness and contains a lot of formulas. As a mechanical engineer I have done these designs in my college life but really shaft design is most difficult part I faced. Of course, this is my personal thinking and you really not needed to worry about that. Some major names under this topic could be Splined shafts, saddle key, sunk key, flange coupling, flexible pin coupling and much more.

Power Screws:

Another important topic is Power Screws. Its really very practical as well as easy and moreover interesting topic. Most of the teachers prefer to start DOME from this topic. Power screw is very commonly used concept these days. Every four wheeler vehicle needs one. We need to learn its properties  viz. single threaded screws, multiple threaded screws, square thread, trapezoidal threads, self locking power screw.

Mechanical Springs:

This is second good part after power screws. Here, we get to learn helical springs, helical compression and helical tension springs, leaf springs, concentric helical spring, telescopic springs. This part is also very practicable and interesting. Just it have somewhat harder and more formulae than power screw part.

Joints:

This part explains a lot about designing the joints in mechanical stuff. Here we need to learn two major distinctions, Threaded joints and Welded Joints. Both have own sets of formulas and pretty different concepts. Comparatively, welded joint is somewhat simpler part than threaded joints.

Fluctuating Loads:

This is one of my favorites. When we initially start studying this part it looks damn dangerous. But in actual its very simple, some logarithmic formulas frighten us from such a good topic and really its mark giving topic any way.

So, I have covered the stuff about Design of Machine Elements.

Thanks for Reading.

According to syllabus of University of Pune, Fluid Machinery is third year second semester subject. As name suggests, we got to study tonnes of machines related to fluids, their performances and much more. As per university pattern complete subject is divided into six main units. Each unit is composed of similar topics. In exam each unit is asked for about 16 to 18 marks.

Introduction to Hydrodynamic Machines:

This is, as usual, fundamental topic which teaches us basic and creates foundation of subject so one may guess as relatively easy topic. And that’s true here. It lightens us with concepts like hydrodynamic head, fundamental equation, efficiency, hydraulic efficiency etc.

Impulse Turbine and Reaction Turbine:

Each of the above are complete unit itself. So relatively important topics and interesting though. Both have similar kind of calculations like velocity diagrams, analysis, speed ratio, flow ratio, velocity triangle, condition for maximum efficiency etc. Pelton wheel comes under impulse turbine while Francis turbine, Kaplan Turbine, Deriaz are reaction turbines.

Governing, Performance and Selection of Turbine:

Up till this unit, students are familiar with turbines. Here are discussed various governing methods for turbines, model analysis etc.

Hydrodynamic Pump:

This is another kind of Fluid Machinery. It covers up concepts related to centrifugal pumps like head, velocity triangle, cavitation, NPSH, priming of pumps, specific speed of pump, classification, performance etc.

Reciprocating and Special Pumps:

This chapter is like school of pumps. Here we learn reciprocating pumps, airlift pump, regenerative pump, hydraulic ram, deep well pump, vertical turbine pump and still more. Last unit also covers one more topic that includes fluid coupling and torque converter.

So, this is something about fluid machinery.

Refrigeration and Air conditioning is generally referred as RAC. According to University of Pune syllabus, we study it in third year second semester of Mechanical Engineering. Now, I will discuss details of RAC.

Methods of Refrigeration:

This is somewhat theory part of RAC. It starts from basic evaporation type refrigeration method and covers up basic requirements of the subject. Some of the common terms are COP (Coefficient of Performance of System),  EER, SEER, IPLV, steam jet refrigeration, thermoelectric refrigeration, ultrasound refrigeration, air refrigeration system, carnot cycle, reverse carnot cycle, boot strap system etc.

Vapor Compression System:

This is most common refrigeration technique in the world. It contains most basic 4 processes. This system needs very good refrigerants. So along which VCC (Vapor Compression Cycle) we need to study refrigerants, their properties like classification, ODP (Ozone Depletion Potential), GWP (Global Warming Potential), TEWI (Total Equivalent Warming Impact), recycling methods, merits, demerits. After Vapor compression we study Vapor absorption system and multipressure system.

Psychrometry and Air Conditioning:

It deals with air conditioning. It is similar to that of steam table in Applied Thermodynamics. Again we face some more shortforms like RSHF, GSHF, ERSHF, ADP. All of them are related to air conditioning part of the subject.

Components of RAC Systems and Ducts:

Actually duct is different part. Its kinda easy and have own type of calculations. In components part we get to study compressors, their types, merits and demerits over each other, thermostatic expansion valves, capillaries, charging of refrigerant, maintenence etc.

Its really good subject but I feel it somewhat hard. It is also good for further career. Many people do post graduation in RAC.
