harmonic oscillator - Relation between shm and circular motion


I recently read in a book that combination of two simple harmonic motions of equal amplitude in perpendicular directions differing in phase by pi/2 is circular motion. I don't seem to understand this because I am not able to figure which two forces in circular motion are acting to cause two different simple harmonic motions.


Any explanation would be thoroughly appreciated
