1@nishant bhaiya... if u feel this question is a damn useless one (which is very usual to think as it will never come in any exam..) .. then i will delete this one within a minute...
gave this one jus for fun :P
1let displacement of k1 is x1 .. k2 ka x2... like dat...
now the restoring force in each string is..
1) F for k1,k3,k4,k5,k6,k8,k10,k11.
2)and 2F for k2,k7,k9.
now from the constraint eqn,
F(1/k1 +1/k3 + 1/k4 +1/k5 +1/k6 +1/k8 + 1/k10 + 1/k11) + 2F(1/K2 +1/7 +1/K9) = -x (total extension of the spring attached to mass m)
ma(1/k1 +1/k3 + 1/k4 +1/k5 +1/k6 +1/k8 + 1/k10 + 1/k11) + 2F(1/K2 +1/7 +1/K9) = -x
now write it nicely in the form of a= - K'x/m then find time period..
then over.. :)
33Noooo Mechanics can never bigad sakta.. no one can never forget it as theres nothing to remember in it unlike bloody chemistry....
Waise i was right for the fourth time today ;)
1ya u r rite priyam ..me 2 ........did mech in 11th ..........so dat was gud.then stared wid elx part ....then mech bigda .and elx was f9............
nw both suck!
33Last year i generalised this type of pulley spring time period but God knows where i kept the copy and now i am not intersted in mechanics as i was in 11th when it was taught..... now its all chemsitry...
1@integrations,
well main jaha padhti hoon... waha hume ek sir ne bola hai ki kaisa karna hai...
1woh diagrm buk pe utarneke liye hi 3 mins jayenge
btw yeh ssum aapke dimag ni upaj hai?
1arey wah scholiiiiiii ................(3 cheers 4 u )bt at d first luk it seems .......crap............hadh hai springs ki
1@abhisekh,,,
no yaar... they wont ask it in any xam... its jus like dat... :P
but the fun is in doing it in 3 mins :P
1i mean yeh sum aapne khud banaya hai...... ??
ya kissi buk se hai ?
1@integrations..
wat did u tell ?
i din get you... am sry :(
pls tell in eng naa.. :P
1waaahh aur main sooch raha tha ki 3 min Q ka hi part hai aur confuse ho raha tha :)
33Ufff
2-3 spring se concept check nahi hota kya jo 11 springs.. Ye sirf bewkoof xam me aega :P and all with different spring comstants...
:(
