A rod OA rotates about a horizontal axis...

A rod `OA` rotates about a horizontal axis through `O` with a constant aniclockwise velocity `omega = 3 red s^(-1)`. As it passes the position `theta = 0`, a small block of mass `m` is placed on it at a radial distance `r = 450 mm` if the block is observed to slip at `theta = 50^(@)` . Find the coefficient of static friction between the block and the rot
