60mm A composite beam consists of an aluminium core (EA1 = 70 GPa) with steel strips at the top and bottom (Esteet = 210 GPa). The beam is carrying a bending moment of M = 15 kNm about a horizontal axis. 205 Al a) Create an equivalent cross-section made entirely of steel. b) For this equivalent cross-section, determine the distance from the 20mm I s bottom of the beam to the Neutral Plane, and calculate the second moment of area (I). c) Determine the radius of curvature of this equivalent cross-section. d) In the original composite cross-section, calculate the maximum bending stress, in the aluminium, and in the steel. Calculate the parameters using the formulas below: Write your values here The last two digits of your student number (nn) Height (h) h=0.4x n +100 mm mm
