For the given curved beam (as shown) with a rectangular cross section, calculate the distance of the neutral axis from the center of curvature. Express your answer in mm, up to 1 decimal place.   13) The bending moment acting on the curved beam with a rectangular cross section is 25 kN-m. What is the bending stress at point B? (Answer must be in MPa, up to 1 decimal place. Add a minus sign if the answer is a compressive stress.)
