А. TIK В w R M b JA(1/r)dA=bóln(r/r) The figure (not drawn to scale) shows a curved I-beam of given section and inner radius subjected to a bending moment. Given Sections parameters, 15 mm. , - 115 mm, 100 mm and he = 12 mm, Inner radius R. - 30 mm and bending moment M = 146 MPa Calculate the radius of curvature at the beam's section centroid, the radius of curvature at the neutral axis R and the stress at point B Enter your answers in the boxes below. The answers are acceptable within a tolerance of 0.01 mm for the radi and of 0.1 MPa for the stress. mm (3 mark) R: mm (3 mark) MPa (2 mark) 18 marks
