UNSYMMETRICAL BENDING. The general bending stress equation for elastic, homogeneous beams is given as. (II.1) where Mx and My are the bending moments about the x and y centroidal axes, respectively. Ix and. Iy are the second moments of area (also known as moments of inertia) about the x and y axes,.

Note: in our expression for ?q the q flows "out" from the end of the section under consideration, whether the section is cut from the left or right of the cross section. At the beginning of the section the q flows "in". Examples: ( )1. q s. 1 s. 1 s. ( )1. q s. ( )0 q. ( )0 q in both these cases. A. A. ( ) ( ). (. ) (. ) 1. 0 z yz y yy z y yz z zz.

25 Oct 2010 Abstract. The elementary theory of the bending of beams is restricted to the case where the beam has a cross section with at least one axis of symmetry. In the present chapter, we shall generalize the theory to beams of arbitrary cross section. All the remaining assumptions of the beam theory will remain
