Luck also may be a factor. But when you work more and more hard you become more and more lucky.

Good information! IITJEE shd learn from AIEEE admission team. They conduct 7 rounds of selection to see that most of the seats r filled. They shouldn't include other than IITs in the selection process. The JEE list shd further be expanded to see that some unwanted or not-so-popular courses have takers. At the end, I propose, a spot selection for the vacant seats from JEE qualified candidates like NITs can be started.

One out of every four IITJEE qualified candidates is from AP. So u can expect them everywhere.

Thanks for the responses!My son got selection in IIT Bhubaneswar(Electrical). With an AIEEE rank of 2135 he may get NIT Trichy(Electric). Hence I was in a confusion. I think we will go for IIT.

IITJEE has published the closing ranks of various courses in their website. Pls check up. This will give an idea about 2nd round closing ranks. I feel in the 3000 range there will be a shift of 200 ranks in the second round. This year an apathy towards new IITs is evident compared to last year. Check the link below: http://www.jee.iitm.ac.in/openclose2011.php

New IITs, is govt taking students for a ride? The conditions of new IITs are inferior toeven an ordinary private engg college in India. Even after three years govt could not do much in building the permenant campus. Many students r forsaking prestigious NIT seats and joining new IITs expecting IIT tag to do some miracle in their life. Govt should have started admission in new IITs after the setting up of new campus. This make shift arrangement appears to be rediculous.We are in a fix.Pls advise

I think no. It is possible incase of NIT. For IIT u r forced to accept higher options if allotted!

I wish best of luck to all the IIT aspirants!!

Dear experts, Govt of India had recently started an institute called Indian Institute of Space Science and Technology. www.iist.ac.in/ They offer B Tech in Avionics,Aerospace and physical sciences. Earlier they used to take students from EML of IITJEE. Now they conduct their own test. This year the test is on 16.04.11. I would like to know what is the standing of this institute? Students have to sign a bond that they will serve ISRO for 5 years and the entire expense will be born by Govt. during the course. Another drawback is that you will be always under a scanner of Govt sleuths if you join ISRO. But we can work for our Nation's progress rather than some multinational company. Pls advice whether it is worth joining IIST if one gets admission in NITs of south India? If yes which branch is better?

Centre of mass can lie out side the body. For a ring it is at the centre which is outside the body. For a 'C' shaped body also it is outside. There are plenty of shapes like that. COM is only a point where mass can be imagined to be concentrated for analysis purpose. When it comes out side we can't physically use this point for supporting the body like a pivot.

Present example is a case of periodic motion. Here displacement, velocity and acceleration are not varying in a sinusoidal fashion. So it is not SHM.

Even if you get first rank in AIEEE u should go for IIT with a rank of 1073. There is absolutely no room for any confusion!!!!!

@Nimisha Radhakrishnan If centre of mass is at fulcrum it is not necessary that beam should remain horizontal. If the beam is inclined, still the moment on both sides will be same. So there will be no net torque even in inclined psition. I feel that the fulcrum should be slightly above the centre of mass so that any small inclination will raise the centre of mass causing imbalance. So due to gravity the COM will come to lowest stable point ie below the fulcrum. Thus beam will remain horizontal always if masses on both the pans are equal.

Viscous force of air is not that small. When objects fall the drag force due to air is proportional to velocity of object. So when an object falls there will be a reduction in acceleration but not velocity. Velocity keeps on increasing till a stage where drag force becomes equal to the gravitational force on the fallin object. This velocity is termed as terminal velocity. Rain drops fall to earth in terminal velocity and without any acceleration. Most of the falling solid objects even burn off/melt before reaching earth due to air friction like meteors.

Joining a coaching class is not a must for clearing JEE but by joining some reasonably good coaching centre surely you are going to enhance your chances!

I understand that your question is why the beam remains horizontal if weights on both the pans are equal. The pivot or the fulcrum of the beam is kept at a location slightly above the CG of beam. So when in inclined position the CG of beam will not pass through the vertical line below the pivot and this eccentricity causes a correcting moment which brings the CG to the vertical line and beam becomes horizontal. In other words when in inclined position the CG of beam will be in a slightly raised position. Naturally the beam has the tendency to bring the CG to the lowest position due to gravity where it is in stable equilibrium. When the masses in the pan are unequal the differential moment due to this unequal weight becomes predominant and beam will come to an inclined position. Another point to be noted here is even if the CG of weight and the CG of object being weighed are at different heights it doesn't affect the beam balance. It will remain horizontal if weights(masses) are same. It is because the pans are hung using chains which will take only tension and not moments.

It is generally told that getting into IIT is difficult but getting out very easy. Impression of professors about the student is very important there. All the tests are conducted by them. They have to just submit a table with grades of student for the subject taught. I think that they don't have to tabulate marks obtained or submit question paper/answer papers to academic section. There is no external exam. Teacher himself is the examiner! I feel that this system is doing a lot of damage to students acadamic excellence.This was the practice in 80s. Now also,I am afraid, things are more or less like this only .All the IITs together can form a consortium and conduct external exams and valuation can be done at other IITs. This will not increase the work load of teachers.
