1I THINK QUESTION ONE IS NOT OF S.H.M
IF WE ROTATE THE ROD IN A.C.W DIRECTION THEN THERE IS NO ROLE OF K1 AND M1 (THE STRING BECOMES LOOSE AND DO NOT EXERT ANY FORCE)
IF WE ROTATE THE ROD IN C.W DIRECTION THEN THERE IS EFFECTIVE ROLE OF K1 AND M1
49I QUOTE................
""IF WE ROTATE THE ROD IN A.C.W DIRECTION THEN THERE IS NO ROLE OF K1 AND M1 (THE STRING BECOMES LOOSE AND DO NOT EXERT ANY FORCE)""
I do not agree................[2][2][2]
1@subhomoy~~ATGS
I AGREE THAT MOTION IS PERIODIC ((((BUT NOT S.H.M))))
(FOR UNDERSTANDING TRY THIS QUESTION IN PARTS .i.e, WHEN ROD IS CONNECT ONLY WITH ONE OF THREE COMBINATIONS OF STRING AND SPRINGS) IT WILL SHOW THAT IT IS NOT IN S.H.M WITH M1 , M2 , K1 , K2
1subhomoy~~ATGS
SECOND QUESTION IS ALSO NOT FROM S.H.M
lol
lol
ROTATE THE BIGGER ROD IN A.C.W DIRECTION (THE STRING BECOME AGAIN FREE)

1we don't get any very tough problem in IIT ...
all questions of IIT Entrance are checked at least 100 times by IIT teachers ...
all questions will be conceptual with little calculations....
so don't worry ...we are able to get ranks in top 500...[1][1]
