In the figure shown below, simply supported beam with H-shaped cross section. Knowing that the length of the beam is 8 m, the distance between support A and the starting point of the distributed load is 1 m and the distance between support B and the end of the distributed load is 4 m. Find the following: a) The second moment of area, the location of the neutral axis and the distances from the neutral axis to the top and bottom surfaces. • Take the bottom surface as a reference for you calculations. b) The maximum tensile and compressive bending stresses in the beam, knowing that the maximum bending moment is at x = 4 m from the left of the beam. 120 mm 30 mm 30 mm A 4 KN/m 40 mm 100 mm B 30 mm
