Linear force acting on axis of rotation


An uniform rod of known mass and length (m and l if you like) is rotating relative to an axis of rotation located at one of its ends. The rotation is frictionless and the angular momentum at a particular moment, ω, is also known. Can somebody please tell me the formula for the linear force (if any) acting on the axis of rotation at that particular moment?
