A New Interpretation of the Hereditary Behavior of Self-Sterile Plants

GENETICS: EAST AND MANGELSDORF the torsional problem of curved beams is reached also for those sections, with no further limitations than those existing in the solutions of the corresponding torsional problem in straight members, and the postulation of the principal of superposition.If the forces applied are not pure couples, they can in each section be reduced to a couple and a force.This force will in general cause in the further sections an additional bending around the y and z axes, which will be added to the expressions of My and M8 in equations ( 2).This method can also be used for non-prismatic beams provided the variations of profile are sufficiently slow as to make the disturbance caused thereby on the stress distribution negligible.1 The moment vectors M,, My, M2 could also be obtained by graphical addition of the vectors AA',hBB', etc., and subsequent decomposition of the resultant vector into the s, y and z components.2 For complete treatment of curved members with circular, elliptical and rectangular *crdss-sections, see Paul
