ergonomics and aesthetics

this is the one of the valuable example , iam sorting from the book i read.
this will explain how a such a tiny concept or observation is effecting the whole system.

did u ever think why the position of brakes and acclerator is arranged in a specific arrangement,i.e brake is always above acclerator pedal? why it is not below acclerator? how much it should be below brake pedal? and how this whole thing is going to effect he respective process?

so here i will giv answer to all the above said question. The brake pedal is above the accleraor because it is very important for the driver to remove his foot from acclerator to apply breake otherwise by mistake he can apply acclerator in the place of brakes if both of them are in the same plane. and also brake can not be below the acclerator because for the proper actuation of brake it is necessary for the exact and full application of brake which is not possible by a short leg span person if it is below acclerator.
the optimum height of the acclerator is 2.5 to 3 cm below the brake pedal.

so through this u can understand the importance of ergonomics which is going to become the most importnt thing for the designing of the vehicles.

quotas are really worthless...........

we were opposing the OBC quotas not because of any irrelevant reason .. this is proved by the result what u can see in most of the newspaper ....

Yes u can view it in TIMESOFINDIA

Down the years, IIT deans have faced the brunt of political interventions. When the first batch of IIT-Delhi students graduated, 47 of the 53 reserved category students failed. The dean was summoned. Recalling the meeting with the "big fat man", education minister Nurul Hassan, P V Indiresan said, "He kept his bulky hand on my shoulder and asked me, 'Professor, yeh kya kar diya?' (Professor what have you done?)" Little has changed. Only two months ago, IIT-Delhi was pulled up by the Minorities Commission for asking 20 reserved students to pack their bags because of "very poor performance".


this is really shameful for such a reputed institute to have vacant seat ... which is a great loss to infra and also. to such reputed professors who are compel to teach in half filled class rooms

late comer

this is my new post after looooong time...... i was not busy with anything else but i was bit lazy.
now i am back..... in my old but little but amateur profession yes of course.... writing yaaar
this post is little bit informal in nature but i think it make the concepts more clear....

before writing something i wan to say , i got placed in TVS MOTORS good company regarding R&D and lot of other features.....

in this post i want to express my views in the field of JOBS in core industry
i wan to say all the core engineering guys wait for your core companies and better to there ... it is better option i thinkkkkkkkkk....

Man Behind NANO (peoples car)

*
New Delhi: When he first joined Tata Motors 16 years ago, Girish Wagh had no idea he would one day head the companys now-legendary Rs 1-lakh car project. Although he was part of the Indica vendor development team in 1997, Wagh was actually reluctant to get into full-scale product design with the Ace.

He remembers how Tata Motors MD Ravi Kant hand-picked him for the job and convinced him that it was as important as the work he was doing with the companys excellence group. That was December 2000. The Ace rolled out in May 2005 and almost singlehandedly helped beat a recession in the commercial vehicle space.

Impressed by his ability to deliver under tight deadlines, chairman Ratan Tata and Ravi Kant decided to move Wagh to the small car project in August that year. Almost painfully media shy, the Nanos strobe-steroidal launch this week was one of Waghs few public appearances.

A mechanical engineer from the Maharashtra Institute of Technology, which was followed by a post-graduate programme in manufacturing from Mumbai B-school SP Jain Institute of Management and Research, the 37-year-old Wagh has had a pretty dramatic career at Tata Motors. But nothing comes near the Nano experience. Heading a 500-strong team, Waghs biggest challenge was to define the products specifications as they went along.

Unlike the Ace where we knew what the necessary specs were, in this project all we had was a cost target, he says. That and the fact that it had to be a real car which met all the regulatory requirements.

The small car team had already put in about 18 months work by the time Wagh came on board. The R&D team was in place and work was on to get a fix on the styling, packaging, engine and transmission. Because there were no guidelines, the team used the M-800 for comparison. The idea was that we had to achieve at least this much and more, says Wagh.

As we went ahead, we redefined performance specs. As recently as nine months ago, we tweaked the engine to increase the power. The team also decided to launch the car with a manual transmission instead of the earlier-announced continuously variable transmission (CVT).

The CVT will come but the first variants will have a four-speed manual. Widely known as one of Tata Motors new bunch of engineering whiz kids, Wagh enjoys a formidable reputation in the company. A stickler for perfection and a hard taskmaster, Wagh is the first to admit that the Nano experiment had its own share of hiccups. Part of the problem was the constantly evolving design. His solution was to leverage the collective knowledge in the company.

In a somewhat hidebound company like Tata Motors thats never be easy. But then folks inside knew that this was no hypothetical project, the chairman had made it amply clear that he wanted it done. Ravi Kant also made sure the team was insulated from all these pressures. So by the time the project hit top-gear, the R&D team, vendor development team and manufacturing team were all working together, says Wagh.

That may sound easy but the ability to take inclusive decisions without losing the way is a tough call. No wonder, Tata himself is more than generous in his praise for Wagh. Girish is a terrific guy and has displayed enormous leadership qualities, he said, just after the Nano launch.

He takes over a responsibility and sees it through. Of course, no one is indispensible and Telco did go through many years of innovation without a Girish Wagh. Theres a terrific spirit in the company and we try to identify, motivate and empower that spirit. Girish is part of that process, he said.

Now that the peoples car has been unveiled, Waghs challenges are hardly over. Tata Motors must prove that the seemingly incredible design specs hold up at the manufacturing stage too. Product quality needs to be consistent too, something the firm isnt well known for. Although Wagh wouldnt say, insiders say enough quality assurance systems have to be put in place at the upcoming Singur plant.

But Thursdays high-voltage launch at the AutoExpo will no doubt ensure that Waghs career gets another turbo-charge. If the Nano manages a similar product record, it could make the self-effacing Wagh one of Indias most sought after auto engineering brains.

Indias growing importance as an ultra low-cost auto engineering hub means people like him will call the shots in the next phase of growth. For Wagh, the future is here and now.

NIRMAAN an inspiration

NIRMAN
From the basic knowledge of science and technology we can say that mass,energy can neither be created nor be destroyed but we can convert it from one form to another that is what literally meaning of 'NIRMAN'.

Yes NIRMAAN deals with the immense appetite to create,sharpen and chisel the ideas and pervasive tasks. Let us now come to the very core idea . NIRMAAN is a part of national level technical fest 'DAKSH 08' commencing the part of mechanical and civil engineering in SASTRA UNIVERSITY.

NIRMAAN includes various technical events related to mechanical, civil and structure field. the list of the events and full details can be get from ......
www.daksh.sastra.edu

Events of NIRMAAN will test your mental ability ,intelligence and most importantly your smart work. it have contraption which compel you to make simple things in different manner such that things become complicated and believe me contraption will teach you very basic concepts of science.. for better understanding you can go through .........

http://video.google.com/videoplay?docid=877124040670507488

another one is magnum, which will tweak your projectile concepts.Bomberman have taste of your mechanisms power and ability to do the given task in shortest possible time. Hydrotrax includes use of gravity and designing ability to make the model. monster truck is a chance for automobile seekers. build o zone senses structural knowledge.
so make yourself proud,use this opportunity to show your talent and be a part of the huge gathering of innovators "NIRMAAN SOMETHING..........."

industrial and academic approach.....what a diiference.????

Really there is great difference in industrial and theoretical approach.....

I can give a relevant example given by my prof.(professor)

Actually in designing gear arrangement we have to design wheel (bigger radius) and pinion (smaller radius gear) . In such design situation what we know from theoretical basis is we should design, considering pinion because for one complete rotation of wheel the angle of rotation for pinion is more.so it's wear rate will be more.

And we have to take maximum stress for pinion .here only we have to see the contradiction from industrial design for same arrangement . In industries it is economical to go for designing wheel rather then the pinion, because it become inexpensive to manufacture pinion compare to wheel.

So in industries they are practising to make the gear arrangement in such a way that pinion Will never be stronger then wheel . This will allow comparable wear to pinion then wheel ,and it is inexpensive to change it. So like this we can have large number of examples regarding the difference between industrial and academic approach.

Regarding this refer to article in 'THE HINDU' dated 5 January 2008, according to D.R.D.O "WE ARE HAVING RESOURCES BUT SCARCITY OF MANPOWER ."

This is the pure result of contradicting behaviour of both approaches. D.R.D.O seeking for experienced and dedicated research fellows to work on more complicated experimental work. But until and unless we will fill the gap between academic and industries. It become very difficult to surpass this scarcity.........

design books and URLs

Most of the books on design (mostly Indian author) gives knowledge of designing mechanical parts
like springs,different types of bearing,shafts belts and all other parts of mechanical and structure systems ,but I never found any book having details of whole design process,
so in this context I found some very good books having answers of my different questions regarding design process....

1. George E Dieter .

2. Joseph E . Shigley.

3. Ullaman.

4. Yousef Haik.

obviously different other prominent authors are there but if u want to have a basics of design then all above said books are very good.
for details regarding different e books we can go for

http://gigapedia.org

here we can get many e books free of cost.

other then this for recent trends of design news we can go for
http://www.designnews.com

we can have access to design link of ASME also....
http://www.asmedl.org/MechanicalDesign

soon iam going to provide most of the design urls in blog........
