Description:
Samaras are highly specialized forms of “flying” fruits that some species of trees produce for the dispersal of theirseeds in their environment. The flight of a samara is always a highly elaborated form of mechanical motion, andan excellent opportunity for application of both Intermediate and Analytical Mechanics to a natural phenomenon.One of the more interesting cases, the passive flight of Triplaris Caracasana, which is a combined motion ofvertical translation and simultaneous rotation, is presented here. A Newtonian Mechanics model is elaborated, andsuccessfully confirmed, using a variety of different and accurate laboratory measurement techniques including onebased on the chopping a laser beam. The motion of the flying samaras is indeed appealing and should be found ofgreat interest for Analytical Mechanics and Fluid Mechanics and as shown here for Intermediate Mechanicscourses.
