| Summary, etc. |
Se realizó un estudio tecnológico en la madera de Pinus engelmannii Carr., P. douglasiana Martínez, P. leiophylla Schltdl. y Cham. y P. herrerae Martínez de El Salto, Durango, para conocer el esfuerzo mecánico a la extracción de clavos de 2.5 x 50, 3 x 63.5 y 3.3 x 76.2 mm, así como de tornillos de 4 x 50 mm para madera conforme a la norma ASTM-D1761-88. Se realizaron 40 repeticiones por especie para cada tipo de clavo y tornillo considerando los planos radial, tangencial y transversal de la madera. Los valores obtenidos se ajustaron al 12 por ciento de contenido de humedad. Los resultados mostraron una resistencia mayor a la extracción de clavos en la madera de Pinus engelmannii con 61.89 kgf; el plano radial de la madera exhibió 50.35 kgf y los clavos de 3.3 x 76.2 mm registraron 53.33 kgf. En los tornillos de 4 x 50 mm, la mayor resistencia la presentó la madera de P. douglasiana con 315.09 kgf |
