A composite beam 225 mm wide x 300 mm deep x 4 m long is made by bolting two 100-mm- wide x 300-mm-deep timber planks to the sides of a 25 x 300-mm structural aluminium plate. The moduli of elasticity for the timber and aluminium are 8 GPa and 73 GPa, respectively. Determine the maximum tensile flexural stress in each of the materials if the composite beam is simply supported and carries a concentrated load 30 kN in the centre of the beam. 25 mm 300 mm ㅏ 100 mm 100 mm
