    hi bhaiya, long since I came on the blog!
    bhaiya, I am not able to get the figure. is the rod BC moving down with w i.e. rod AC is sliding on that part
    2w for this one
    OR is it that BC is rotating making a cone.
    w for this one
    OR is it rotating about the vertical axis passing through its center.
    couldn't get it
