DescriptionWood of spruce pine, Pinus glabra Walk., was factorially segregated by moisture content (0, 10, and 18 percent), specific gravity (less than 0.45 and more than 0.45), and extractive content (unextracted and extractive-freE), and the kinetic coefficient of friction on steel (having surface roughness of 9 microinches RMS) determined for tangential earlywood, tangential latewood, radial, and transverse surfaces. Two directions of pull were considered for each surface. The friction coefficient was at maximum for the unextracted transverse surface of high moisture content pulled parallel to the rings (avg. 0.263). It was at minimum for the extractive-free transverse surface of high moisture content pulled perpendicular to the rings (avg. 0.165). among unextracted samples, it was least for the tangential latewood surface of dense wood having intermediate moisture content pulled perpendicular to the grain.
