A horizontally oriented uniform rod AB of mass `m=1.40kg` and length `l_0=100cm` rotates freely about a stationary vertical axis `OO^'` passing through its end A. The point A is located at the middle of the axis `OO^'` whose length is equal to `l=55cm`. At what angular velocity of the rod the horizontal component of the force acting on the lower end of the axis `OO^'` is equal to zero? What is in this case the horizontal component of the force acting on the upper end of the axis?
