Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.therfore aA= aB =a
aBA = aB-aA = 2a
aBG = a
while applying virtual work here do i need to consider component of T (written in blue) perp to wedge
this seems right to me
no idts the accel of block B rel to A would jus be 3a right?
relative to A krlo and then end mei wrt ground kr lena 🙂
ismei jo mein aB consider kar rha hu woh wrt wedge hai ya wrt ground
the ans is correct method isnt
Yes ig th acc u grt when applying virtual work is wrt ground, for relatice u need tk do plus or minus shit
@Real potato
iss thread ka ques dekho
ismein bhi T.a mein a of B wrt wedge leke aata hai
nah he’s correct
The wedge itself will be moving for relative we gotta do that plus minus thing
can u share your soln
Wait
for this one
Or the
Other one?
yeh ho gya toh dusra apne aap samjh aa jayega ig
ruko krta try
@CorrodedCoffin
And b wale part me
jab virtual work lagayega ya t.a krega to wo slant wale string ka consider ni krege
acc of b =3a ayega wrt to wedge
String constraint se samjhne ka try kr
If wedge left move kreg to jo l length hai rope wall or wedge ke beech me wo 3times decrease krega cause teen string attached hai with wedge
Ä°slie block ka acc 3times wrt wedge lena pdega
Tab jake sari string length constant ayegi
fir uska component tu le skta hai x or y me
aise wedge wle que me ig ek br u should check strings kese length change krege taki thoda samj aaye pulley problems me to virtual work is a no brainer thing
sorry late reply
acc to key accn of B wrt A is 2a and accn of B wrt ground is a where a is accn of A
this is from phy galaxy and tbh i dont trust the answers in it sometimes
acc of b wrt ground agar a hua to string hi slack kr jayega
Wedge left me jara hai to wo do string ka length a acc se kam krra hai
Usko counter krne b ko 2a se to jana pdega
phy galaxy L ig
aBA = a and aBG = 2a then ig
from this discussion we conclude that if the wedge is moving apply virtual work with accn of block wrt incline
wedge par sirf T nahi lagega
Yup
f.. what a blunder
but i think u got it right?
yeh diagram dekho
Yeah mb me wo niche wale pulley ka T lena bhool gaya
