The beams shown in the figure are subjected to bending moments M = 250N ? m. Each beam has a rectangular cross section with height h = 44mm and width b = 10mm (perpendicular to the plane of the figure).
(a) For the beam with a hole at mid height, determine the maximum stresses for hole diameters d = 10, 16, 22 and 28mm.
(b) For the beam with two identical notches (inside height h1 = 40mm), determine the maximum stresses for notch radii R = 2, 4, 6, and 8 mm.
