BENDING RADII OF DENSE, FLAT-SAWN DOUGLAS FIR AS AFFECTED BY SLOPE OF GRAIN AND KNOTS

摘要

The overall purpose of this study was to investigate the bending properties of dense, flat-sawn Douglas fir in regard to effect of slope of grain and knots on magnitude of bending radii when bent in the dry unheated state. The investigation is divided into two separate parts; each part incorporating its separate objective.
