The square plate of side length 2b pivots about its center point O against the action of four springs, each of stiffness k. Each spring is attached to the corner of the plate at one end and to the center of a slotted collar at the other end. As the plate rotates, a rod slides through the smooth slot in the collar and deflects the spring. Determine the frequency ƒ_n of small oscillations about the equilibrium configuration.
