1.	A platform P is moving with a velocity v_(P) over hemispherical shell. A vertical rod AB passing trhough a hole in the platform is moving on the shell and remains vertical. There is sufficient friction between rod and shell to stop the slip. C is the crown of the shell and O is its cenre angle BOC=theta at any instant. find the velocity of point B in downward motion at that instnat:
Answer» <P>`u_(p) SIN theta` `u_(p) cos theta` `u_(p)TAN theta` `u_(p) cot theta` SOLUTION :`(x)/(y)=tan theta` `x=y tan theta`
