It was studied the physical-mechanical properties of the Fernán Sánchez wood (Triplaris cumingiana Fish. Mey.) coming from Quevedo and Balzar. The objectives were: to determine the heartwood and sapwood percentage of the trees, the physical properties in green and anhydrous state of the wood, the mechanical properties in balance state and the main physical-mechanical ifferences of the wood. 10 trees of Fernán Sánchez were collected (5 in Quevedo and 5 in Balzar) with ages among 13 to 18 years. Of each tree two logs of 2.50 m of long was obtained and of each log a central plank of 10 cm of wide by 2.50 m of longitude was obtained of which beams was extracted and finally the specimens. 60 specimens were elaborated (6 specimens for tree) for the rehearsals of the physical properties. For the study of the mechanical properties 60 specimens were elaborated (1 for each rehearsal for tree). The methodology used for the study of the physical and mechanical properties was based in the norms ASTM D 143-94 (American Society for Testing and Materials). The results showed that significant difference doesn't exist among the wood of the two areas. The wood of Fernán Sánchez of Quevedo and Balzar presented medium density, for what has better use possibilities in the production of furniture and cabinets, frame in constructions, molds, carpentry in general, boardings, doors and windows, among the main ones.
