“…A number of studies have used elements of beam theory to detail cross-sectional strength and geometrical properties of human and fossil hominid bone (Koch, 1917;Backman, 1957;Allen et al, 1968;Amtmann, 1971;Kimura, 1971;Rybicki et al, 1972;Minns et al, 1975Minns et al, , 1977Lovejoy et al, 1976;Lovejoy and Burstein, 1977;Martin and Atkinson, 1977;Miller and Piotrowski, 1977;Miller and Purkey, 1980;Lovejoy and Trinkaus, unpublished manuscript;Martin et al, 1980. To our knowledge, only Jungers and Minns (1979) have applied beam theory to the analysis of nonhuman primate bone.…”
