Guys this part of the blog is dedicated for education purposes only.
In this,like many other blogs anyone having a question can ask.any.
and other members will answer it..
Okay In This Question the rod exerts a frictional force to oppose the centrifugal force experienced by the 2 idiots. therefore friction=centrifugal force=centripetal force since they are equal friction must cause an acceleration =w*w*r F=M*A M*W*W*R w--angular velocity w=2*pi*20/60 w=(2/3)pi M=15kg R=3/2m M*w*w*r=15*2/3*2/3*pi*pi*3/2 15*2/3*pi^2 10pi^2

ReplyDeletetherefore friction=centrifugal force=centripetal force
since they are equal friction must cause an acceleration =w*w*r
F=M*A
M*W*W*R
w--angular velocity
w=2*pi*20/60
w=(2/3)pi
M=15kg R=3/2m
M*w*w*r=15*2/3*2/3*pi*pi*3/2
15*2/3*pi^2
10pi^2
the two idiots are raghav and richard...:)
ReplyDeleteWhat the hell did u do to the blog!!!... :X
