Problem 1. The Z-Section shown in figure is subjected to the bending moment of M = 25 kN N. m. The principal axes y and z are oriented as shown, such that they represent the minimum and maximum principal moment of inertia. Iy = 0.960 (10) m4 and = 7.54 (103) m, respectively. Determine the normal stress at point P and the orientation of the neutral axis. 100 mm 400 mm 100 mm 300 mm- 32.9 M 057.1 M = 25 kNm
