Rod Constraint doubt
Say we have a rigid rod moving such that both ends of the rod have diffrent velocity vectors in diffrent directions. the velocities along the rod are obviously equal but will the velocities Perpendicular to the rod be equal everytime??

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.they will be in circular motion , use v=r*omega to find them
ultimately the body is rotating
from where would i define r
COM??
i think COM since its such a vague rotation we will ke COM pe rotation
ill do the thing
the point about which rod is rotating
no such rotation
question nahi hai as such
unless kahin se hinged ho and rod pe aur koi particle na chipka ho use com
if another particle is stuck to it then use new com
then com is the way to go
thing is i was just going thru Rod Constraint in NLM and usme we wrote that velocities along the rod are equal and thought of perpendicular velocities came to me
thought it was cool and posted it here in search of insight
ok ji
nice thought
came out to be equal as well
but idk why gut feeling keh rahi hai ki something here is fishy
feels like a one off special case
ig by saying COM ke along rotation
humne generalise kara hai
ek humare coaching ke Physics ke sir bhi resign kar gaye ðŸ˜
he always supported such new thoughts as long as it pertained to our Goals
;-;
what if i try doing not along COM
haa then its coming diffrent
but its always coming in such a way that
the perpendcular velocity with greater Rvector is greater
idk what i got by doing that
mujhe lag raha hai maine idhar r vector me gadbad kari hai cuz V1sin(theta) should be -ve
your situation is this?
dot is com not hinge
huh yea
just that maine angles define nahi kare
and uhhh Vb is in opp direction 💀
yea maine Vb vector galat liya hai
the case still follows
rod constraint se find Vb
then what i like to do is making any one of the point iaor. opposite point pe relative velocity lelo and then find omega using v=r*omega
ohhhh niceee
bhai when we will take IAOR rvector will be taken from IPOR right???
Or from the normal AOR
??
i belive it should be IAOR
since humne rel.velocity bhi to IAOR ke respect se liya
and hum rel. velocity ka use karke hi to omega nikaal rahe
ipor yes
okk
cool
soooo the conclusion of my main question was that it very much depends on the AOR
thanks @hardcoreisdead
