| Need guidance in Shaft Torsion Software Design Posted: 04 Jun 2011 10:17 AM PDT I am a 5th year Mechanical Engineering Student and I am working on a software for simple torsional analysis of shafts. After doing research online, I have defined my project to have the following scope: > Software ability to determine Torsional vibrations > Software ability to determine Longitudinal and Transverse Vibrations > Software ability to calculate General torsion elements (such as Twisting Moment - Torque, Diameter of Shafts, Angle of Twist, Length of Shafts) > Software ability to determine the critical speed or whirling of shafts After this, I proposed to use Visual Basic to design it, but I found out that my knowledge of the language is not sufficient enough to meet the scope of my project. Yet, I am interested in this project because once completed, I believe it will help other students here, in the study of torsional shaft analysis, and my knowledge of the language will be improved especially as related to Mechanical applications. Now my first question is: "What tips do I have to keep in mind when designing this software?" And my second question is: "Can anyone, please help me with materials or ideas that will facilitate this software design especially in understanding the language - Visual Basic?" Thanks for offering to help! |

| Posted: 04 Jun 2011 04:39 AM PDT hey friends, suggest me where to start from as i am just a beginer in this subject...How to proceed n which websites to follow to take some help?? |
| Differences b/w Power Supplies Posted: 04 Jun 2011 04:09 AM PDT Electricity Board supplies electricity, here as 220V and 11kV. The later is again decreased to 220V and then used. My question is what is the need for 11kV supply. I know that they are used in commercial complexes and industries, but why not just 220V? (I'm talking about only 2-phase). Another question: What is the maximum current that i can draw from these supplies? On what does it depend? |
| CCPE 2011- Control, Communication and Power Engineering 2011 Posted: 04 Jun 2011 02:52 AM PDT An International Conference on Control, Communication and Power Engineering is going to be conducted during Nov 07-08, 2011, in Pune, India.

| Posted: 04 Jun 2011 12:42 AM PDT Here is a short description of how DHCP works. DHCP stands for dynamic host configuration protocol. It's a protocol that lets network admin to automate the assignment of IP addresses in network. Each machine connecting to internet using TCP/IP needs unique IP address. Without DHCP, the ip address must to be entered manually at each machine and if that machine moves to other subnet, a new ip adress must be entered. When DHCP is used, new ip address is assigned automaticaly when computer connects to network. How it works :

| Know Your CEan - xheavenlyx aka Varun Posted: 03 Jun 2011 11:45 PM PDT YeY! CrazyEngineers came again with an Awesome and Awesome interview with one of our CE – Stars. He is CEan – xheavenlyx, a Crazy Electronics and Instrumentation Engineer who has contributed about 680+ valuable posts to CE. CEan – xheavenlyx aka Varun Dhanwantri was very active, left, came back, active, left again. And Now He is back again. Varun is passionate about Electronics, Design, Videography, Psychology, Human Machine Interface and interested in Gaming. We are Very Glad to present his words here… Pallavi : Hi Varun, you are a Crazy Electronics and Instrumentation Engineer, tell us more about yourself. Varun : Okay :) Pallavi : How did you get introduced to CrazyEngineers (CE)? Varun : It was back in 2006 while looking for an online forum to discuss "nerd", I came across CE. It felt good to be around people with common thinking. At that time I was also a member of other forums but got out because of some 30 year old jobless pretensions pricks who thought they were gods as all they did was sit on the forums answering questions. Pallavi : Why did you take up this particular engineering trade? What do you like the most about it? Varun : I choose Electronics because I was curious by birth and not having people around to take apart, like in psychology, I took apart electronic devices around the house. Pallavi : What is your favorite pass time? Varun : Siting alone and watching House M.D. with a KFC dinner meal. Pallavi : Seems you are Interested in Gaming; what kind of games do you play? Varun : I started with the classic PC 286 with Windows 3.1 and played F1, Duck Tales and Prince of Persia. Then Doom, Duke Nukem 3D (HOT!) and Wolfstien 3D. I had an Atari 2600 too, ah the memories! Then Sega 8bit, Playstation, PS2. Some of my favorite games are: Parasite Eve, Chrono Cross, Xenosaga/gears, Final Fantasy (7,8,9,10), Silent Hill 1,2,3,4 (the only game that can scare the shit out of me evennow), Metal Gear Solid 1,2,3, No One Lives Forever and a lot more unimportant ones. Pallavi : Who are your idols or inspirations? Varun : Richard Branson. He started his own magazine at a very young age, bought a car when he didn't have a license. Later started a record store and a record label with a recording studio at an abandoned villa, hot-air ballooned around the world and now owns has his own airline. Pallavi : What is the biggest achievement in your life so far? Varun : My biggest achievement has been getting through college without a single back-log while having a physical disability. Pallavi : You are interested in Philosophy! What do you say, If I ask you to tell two good words for our CEans ? Varun : Believe in what you want to get across to people and make it happen. Everyone has ideas, the very same ideas you think no one has ever thought about. Only difference is that some make it happen some just dream on. Pallavi : You are from BITS – Pilani, One of the top universities in India. Let us know the Quality of Education, facilities they provide for BITS students compared to the other Universities! Varun : Not to blow anyone's bubble but it was the same as any other university. In India engineering universities are like factories training engineers like in a production-line for multinationals to use as slaves. There is no research, no independengt thinking. Very rarely if a student really wants to do something different, he or she gets shot down by professors. This is a small problem subset of a larger one. Anyway, everyone who is in university rite now, remember one thing; experiment all you want! This is the time to live your life. Think big and just believe in what you want to do it. If you fail, learn and try again. It's a cliche, but it works. Pallavi : You have a work experience in different fields; you kept on shifting your jobs! What job do you like the most? Varun : Over the years I have worked as a telecom engineer, as a trainee at a paper and packaging factory, a robotics research assistant and as a beer dispenser at a concert. The best experience was as the beerdispenser . That is where I came to know how it feels to die a little of exhaustion. Respect for the people who do this full time. Pallavi : You would love to own more than 2 companies unrelated to each other, one electronic consumer devices and the other an advertising agency with a movie production branch. Why So? How are you preparing to achieve your dream? Varun : That's a very good question. Frankly, I am not doing anything rite now for the two or it seems to me that way. It's internal. Electronic consumer devices for the passion I have and movie production to support the arts. I would surely inform CE community when any of the two come to life. Pallavi : Its really great that you have started two good projects in our CE-Labs section; CE – BOT and Local movie catalog using IMDB. Tell us your experience working with our CEans J Varun : Ah you have done your research for this interview :) Well, it has been a good experience so far. One problem we face is location. Many members live spread around the world so it's difficult to collaborate on projects. Another thing is many members are students who do not have time to join in so we end up with about four or five who are really interested in a project. CE-Bot got on hold because of location and cost problems. Movie Database is going well, but for now it's only me. Waiting for more to join in. Take part in it at: http://www.crazyengineers.com/forum/...ng-imdb-2.html Pallavi : What is the difference you found on CE compared to other techno forums? Varun : The difference is in the kind of education and experience. Other forums have people who are not engineers but just interested in technology, robotics and DIY. On CE we may have a mix of students and enthusiasts where many students are looking for easy solutions and ready-made project files because of our education system. At the same time we have members who are very interested to learn more and expand their knowledge. Pallavi : What changes you found in yourself before and after joining CE? Varun : It did teach me one very important thing. To take lead of things and realizing that people are everything to a project. Without team effort (and a good team) we have nothing. Pallavi : If you are given a chance to take a role in CE, what would you like to have and What would you do for CE? Varun : I would like to have a regional office in Dubai for CE. Work as a Marketing and Strategy Manager and form an umbrella support group for engineers in the region. Have conferences for the members by calling in local professors to cover latest technical topics and encourage growth. Pallavi : Your blogs are so good. What made you to blog? Varun : Really? Are they good? These days technology allows us to share our knowledge with everyone around the world. It feels good knowing you are introducing someone to a new idea. The attention we get from a blog is good too. :) The CE Quickies aka Rapid Fire: 1. Who are the best CEans according to you? Varun : All CEans :) 2. Why your id is xheavenlyx, very different? Varun : Yup and it's pronounced ex-heavenly-ex. 3. If you were given a chance to be a One day admin of CE… Varun : ...will delete all the accounts. The people who really care will join back. 4. Tell us any 3 things that annoy you the most? Varun : Stupidity, religious hypocrisy and the question "What's your favorite Movie?". 5. Define yourself in a single word Varun : I (...hate this Q too) 6. Your biggest blooper till date is? Varun : In university I set up a mystery crystal maze style game to find a box of chocolates for valentines day by solving clues. It was elaborate and took me a week to set up. The end was telling the correct CODE word to our receptionist to get the box from her. The girl who I wanted to give the game to never took it...walked away saying I should "forget it". The game ended with my best friend solving it and us having the box of chocolates over the next week. (They were Ferrero Rochers!) 7. A moment you can never forget. Varun: You know, I never understood this. Do I be very honest or politically correct or think about the kind of audience. If I have to think about the audience then you should not have asked this question. If you expected that I was just another boring person who would answer like everyone else, then I am offended. If you really want to know, I will answer it. But then don't censor it...I will be offended again. 8. 5 years from now, you will … Varun : ...be in a kitchen trying to cook something for my wife because I pissed her off by not talking to her about something she wanted to and I was too tired to listen to her. After the dinner I would wash the dishes and watch a movie of her choice while massaging her feel and pamper her in other ways too explicit to write here. 9. If you were a politician, what will your 5 year plan look like? Varun: Wow, this might be the the other best question. You are really good Sahithi. I would increase the local police budget and get them international training. Hire the best people (some from CE), engineers for civil works, science majors and literature majors after a tough interview process. No bookish knowledge but real life experience. Encourage growth for entrepreneurs and investment opportunities. Increase the minimum teacher and professor salaries and introduce more creative and fun training for them. Make a 20 year plan. 10. What do you want to say about CE? Varun : Thank you...thats all. CrazyEngineers wishing Varun All the Very Best! Hope you have a Good Future And we are proud to have you on CE :) |

| MOSFET/Solid state relay connection to drive high current solenoid. Posted: 03 Jun 2011 08:41 PM PDT Hi CEngz, Facing a new challenge in making "Electronic Fuel Injection System". Using a PWM circuit, we generate a square wave form signal (5V peak to peak). This output signal is fed to MOSFET/Solid State Relays (for switching ON/OFF) to drive a solenoid operating at high current (20A) & High voltage (24V) from 2 car batteries connected in series. The ON/OFF takes place @ the rate on 25 times per second. Can anyone suggest a part/item or a complete circuit diagram along with the connections for the above requirement. The PWM circuit can be seen at "http://www.dprg.org/tutorials/2005-11a/index.html" Any help would be appreciated. Thank You. |
