WebAs raindrops grow large they become increasingly unstable. With continued growth they will eventually become so large that they break into smaller frag ments. Discussions concerning drop breakup (e.g., Mason, 1971; Brazier-Smith et al., 1972, 1973; McTaggart-Cowan and List, 1975; List and Gilles pie, 1976) have usually differentiated between two Web4.1.3 Oscillations described by Duffing equations We consider here different types of natural oscillations in an oscillator de scribed by the Duffing equation x + ax + bx3 = o.
