That is, o, has the form o, = a + by, varying lin- early from oxb at the bottom edge of the cross section to ơxt at the top edge of the cross section. (a) Show that M, = 0 for this symmetrical normal-stress distribution. (b) Determine an expression for the axial force F, in terms of the stresses Oxb and ox and the dimensions of the cross section, width b and height h. (c) Determine an expression for the correspon- ding value of the bending moment M.
