"When the body topples,frictional force is less than umg"
umg is the max value of friction I guess,so coeffecient of friction

Question

"When the body topples,frictional force is less than umg"
umg is the max value of friction I guess,so coeffecient of friction<max value of friction
I can't seem to understand it well though..also in context to this,tell me why a square body does not topple so easily..i have both the answers infront of me but still i can't seem to understand,maybe someone can explain me? :/

Main doubt:
Till the time f<umg it will topple,when it is equal to umg it will translate..why?

Someone please?

anonymous · Answer

how can you relate between Coefficient of friction and max value of friction!? they are two different physical quanties :P..  and i didn't get your doubt :-/

"When the body topples,frictional force is less than umg""
explain this!

anonymous · Answer

i think what you are saying is when a body topples while negotiating a curve, the Max value of frictional force is less than CENTRIPETAL FORCE required

dls · Answer

no ? :/ lol

anonymous · Answer

thats the case when a body topples :P..

dls · Answer

And what happens when the body topples?
The body moves,but yet frictional force<umg.This is very important point.Students need to visualize this scenario very clearly in their minds.When the body topples,frictional force is less than umg.Also it requires less efforts to move a body.

If this is so..why doesn't a square body not topple so easily?
The reason is very simple.The coefficient of friction needs to be higher than 0.5( i know why :O) for a square body.This does not happen in reality because u=0.5,the surface must be really very tough.

I got the answer to the question but why does it have to be less than umg ?  :/ just a bit confused..

hmm typed too much :P

dls · Answer

that is what is written in my book^^

anonymous · Answer

all i know is something very simple
if the required centripetal force is less than the max static friction between the tyre and the road the body will topple.. as simple as that :-/ search some problem!

more than*

yahan centripetal kahan se aa gyi? :O

dls · Answer

exactly :P

dls · Answer

If the co-efficient of friction=0.2 what will happen to the square?Will it topple or translate?
If the co-efficient of friction=0.6 what will happen to the square?Will it topple or translate?
force for toppling for  a square>0.5mg right :|

dls · Answer

a question,but i would love an answer to the theory ques!

anonymous · Answer

wait.. you are talking about TAKING A TURN right?

dls · Answer

here,maximum value of friction=0.2 which is less than 0.2mg O.o doesnt make any sense and NO WTH?

dls · Answer

just a square llying on table :|

anonymous · Answer

Arggg.. you mean SLIDING!???

anonymous · Answer

LOL. A box is lying on the ground. We are applying a force at the topmost edge from the right hand side.

anonymous · Answer

sliding/toppling.

anonymous · Answer

OHHHH!! :D :D :D :D !!!

dls · Answer

idk which centripetal force is he talking about :P

dls · Answer

lol..

anonymous · Answer

ok ok ok nvr mind.. i thought toppling when you take a turn!! :D

dls · Answer

:/

anonymous · Answer

ok now tell me .. what you mean a SQUARE?? you mean a CUBE right?? not a square lamina lying on the ground right?

dls · Answer

square :/

dls · Answer

square body

anonymous · Answer

squre body!?? :-/.. you mean a 2d lamina???

dls · Answer

HOW DOES IT MATTER ? :/
im telling the force for topling>0.5mg!!

dls · Answer

answer it now! dam

anonymous · Answer

just iamgine a square body.. |dw:1363620293705:dw|

anonymous · Answer

I'm out. solve kr dena. :P

anonymous · Answer

i can't understand square body!?? it is three dimensional body right?? like this?? |dw:1363620388440:dw|
