4 Consider an inflected beam element as depicted in Figure Q4. The z axis is the axis in the direction of the beam thickness at the middle cross section of the beam, and has origin at the intersection with the centroidal (neutral) axis. The beam has a rectangular cross section whose thickness is h = 10 mm, and the width is b = 16 mm. The beam is made of a material with a Young's Modulus E = 210 GPa. Assume a radius of curvature R = 65 m. (3 marks) (4 marks) (4 marks) (9 marks) (5 marks) (25 marks) (a) Determine the second moment of area of the beam cross section. (b) Determine the value of the axial stress o at the top and bottom edges of the beam, namely at z=-h/2 and z=h/2. (c) Determine the value of the strain & at the top and bottom edges of the beam, namely at z=-h/2 and z=h/2. (d) Make a sketch of the profiles of the axial stress and strain along the z axis from z=-h/2 to z=h/2. (e) Determine the applied moment M on the beam cross section. -pe your solution here: _^/2 Z=- Z z = ¹/2 Figure Q4 Total Q4 Neutral axis
