Part A - Normal Strain at a Specified Point Consider the pre-deformation cross-section of a bar, a side view of which is shown in the figure below. h d Ax The diameter of the bar is d = 150 mm. A bending moment is applied that causes the neutral axis to become concave up. What is the normal strain h = 25 mm from the bottom of the bar if the radius of curvature is measured to be p = 5.5 m? Express your answer to three significant figures. View Available Hint(s) = vec ? mm/mm
