in the question it is given that the child is rotating around the pivot on rod. the child is rotating, there will be only centrifugal force acting on it which will try to push it outwards. he is holding the rod so friction force is acting between the rod and his hands. so in order to rotate

this is very simple question. you just need to check the direction of forces. you may see the free body diagram in the solutions that at the maximum angular velocity the block will try to move upward and friction force will act in the opposite direction in order to stop it.

if a particle is kept over a fan blade and surface is friction less then blade passes from below it and particle falls down . my doubt is in q. 30 . the same way above blocks should also get tilted as surface is friction less (Coriolis force) hence some friction is needed to retain the blocks in position . but involving friction will affect our answer. so how is it ??
