guys even i need to know the price...thanx!!

guys i could use u'r replies on my post!!!

hey
we are talking about two different frictions here..
what i think is when we talk bout a frictionless pulley we are talking bout the friction between the pulleys axle is zero...but there is a friction between the contact surface of the pulley and the rope...thus the rope doesn't slip, the pulley rolls....but as no energy is wasted due to friction between the pulley and its axle the tension on the either side of the string remains constant
|
|
|
|
i think both a and d are correct....
considering translation the frictional force always remains same as said in option one. also it opposes translation
but if the cylinder starts rolling the same magnitude of force will support it...
am i right guys??

neil....this amrindar guy is trying to gain salutes by just asking questions without insufficient data....read the initial part of forum and youll understand...
|
|
|
|
neil...what da hell you writing me a letter or something...take da truble to read my first posts yaar..i'm talking bout the same thing
|
|
|
|
sravan tht depends on what direction the bee is moving whether toward the direction of trains velocity or opposite to it or at some angle...

yup you are true man...but then we aren't taking any reference..ie we say nothings at rest....unless we take something is at rest all your learning to get into iit or to become an engineer is bullshit..you know what i mean?? we cannot apply our knowledge of mechanics unless we take earth as reference...if you are interested in such hypothetical concepts vash then you better take up research...m thinking of it myself

hey sanat...my concepts are quite clear i'm trying to help put vash here...and i kno tht pseudo force is there because we are in an accelerated frame..i was trying to explain him in detail..please help out if you can
|

ganny thts exactly the point i made...see my post above...
out of the two forces i have mentioned the one whose origin is explained by some means or say tht force exists when we decide upon a frame of reference..we call that force as real force...which is in this case the force that acts on you while you are sitting in the car...as the force is provided by the cars engine and you are in motion wrt to earth which is our reference
the other force acting on the lamp or the surroundings does not bear any meaning once me assume earth is at rest....thus that force is unexplained and is thus called pseudo force

look amrinder.....
say you are above punjab at 12o'clock...the sun will be exactly above your head....take sun as the reference considering that it is at rest and the earth is rotating...now you must keep your position according to the sun constant...tht means you must always stay exactly under the sun to avoid earths rotational effect..earth rotates at omega=2pie/24hours....now if you want to stay at rest wrt to the sun you must rotate in the opposite direction of the earths angular velocity ie omega.....thus you will land up in harayana if you do so...
are you getting me man??? try referring circular motion a bit from hcv or halliday resnick
|
|
|
|
no man you are not....for that you need infinitely small area...it is not possible localy...it is only possible if the land under your leg starts moving upwards with acceleration -g...ore you getting me?? do you think thts possible...if it would have ben happening earth would have disintegrated in a short while...as every partical would start accelerating radially outward into space...
|

|
thts it man..ive had anough i'm not entertaining you anymore...go and get your salutes from someplace els
|
|
|
|
oh i c what you mean anshuman...perhaps you can elaborate mathematically so i'll understand better..please!!!
