ill try solving it taking torque eqns @ the supports later but if u say it can't be solved, why can't it!? its a unique system isn't it?

Yes I've heard that even our solar system's planets don't trace exact orbits, rather, their orbits keep changing ever so slightly every time they finish a revolution. But with our (12th grade) knowledge of gravitation can we predict that? yaar i don't read solutions posted by ppl, i just...

heavy duty stuff going on in there, maybe this is purely exam oriented, but this was a 2 mark question and i think time alloted wud be around 3 minutes. I am not in2 too much depth of physics, i just know what JEE physics requires me 2 know, and maybe that's way 2 little compared 2 every1 here...

if u can't solve it, its not an unique system. But the geometry says for itself, it is unique! maybe I am not getting the correct picture in mind. cud sum1 over here be sooo graceful and put up a drawing of the rod + supports?

Here conservation of energy implies the 7th class stuff that we learn, "Energy in an isolated system must remain conserved". Initially, only energy is KE of the box. Finally, only energy wud be the heat energy. we equate both of them.

This is a JEE 2 marks question hehe :D and yes i did conservation of energy without thinking too much. I always had this small niggling doubt that Kinetic Energy of a system depends on your frame of reference. I cannot give an alternate definition of temperature or anything of that sort but i...

1 translational and THREE rotational(infinite actually)equilibrium(abt the 3 supports) can be generated. The solution using 3 of the equations will fit the fourth...i took a general case of keeping 2 of the supports at the end and 1 in the middle(coinciding with CoM) and solved it fully.

I did not quite understand ur expirement clearly but i think uve forgotten 1 force...the force which ur applying 2 slide it?? or is it in equilibrium after the CoM is out of the square plate and u have also removed any physical contact with it?

hmmm did u do differential calculus?? ill give u some broad hints...firstly both questions are not log based they are calculus based. Question 1 To uniquely determine any line, we need 2 things, slope and a point thru which it passes. the second condition is already given to us (1,0). To get...

half the posts over here are trying 2 prove that 1=2 or 0=-1 or sumthing like that lol so i thought ill try sumthing of that sort too...its silly...but it fascinated me when i was in class 8. Let a = b where a, b are any 2 real numbers a^2 = ab a^2-b^2=ab-b^2...

this is exactly what we have 2 prove isn't it!? i liked the epsilon proof...it involed no arithmetic that's why lol ;) but see...if u can convince urself that 3*0.3333333... = 0.99999999... then u mite as well convince urself that 1-0.9999999... = 0.00000000.. this wud become a shorter *proof*

well in that case ill state a simpler *paradox*. Consider a game with 2 players A and B in which there cannot be any draw. now either A or B can win, equally likely and exhaustive too...so both have equal chances of winning...so its favouring both...but there's only 1 winner! so if the ATM thing...

hmm...yes...ive become dumb. lol...i meant normal component of velocity there sorry. and well...to find the components of velocity...actually the normal component of velocity will not change coz there no force perpendicular to line joining CoM so i don't think normal component of velocity wud...

we cannot prove, or rather justify that 3*0.33333... = 0.999999... isn't it?? in arithmetic multiplication, we start multiplying from the rightmost and here...we can't reach the righmost. we are dealing with infinity here(infinite number of digits) and arithmetic fails with infinity. Maybe my...

(ab)^1/2 = a^1/2*b^1/2 if and only if ATLEAST one of a, b is Non negative. If a and b are both non negative then (ab)^1/2 = - (a)^1/2*(b)1/2 ;) cheers!
