1 Gry = 941 Mpa Vxy = 0.292 Va = 0.449 1 where the the y axis ent to the growth D) (20 sis). wood is generally considered to be an Oothotropic medenial. For example, the elastic constants for Douglas fis, relative to material (x, viz), are Ey = 12,700 mpa Ey = 1000 Mpa, E = 235 Mpa. Coxa = 1142 Mpa, Gryz = 105 mpa V = 0.39 x axis is longitudinal (parallel to the gooor), is radial (across the gooin) and the a alisis tangent args (acooss the groun At a point Douglas fis timber, the non-zero components of stress are Sxx = 7 Mpa, m= 2.1 Mpa, Zz = -2.8 rupa, xy = limpa. pancipal axis of stress? Determine the oñentation of the principle Determine the strain components ? d) Determine the orientation of the pancipal axes of stain. Mohy's circle may help for (b) and (d) о ) a) Is the Z axis a axes of stress.
