The following figure depicts an aluminum / beam of height h = 0.25 m, width b= 0.2 m, flange thickness ta = 16 mm, and web thickness tw = 12 mm. The beam is reinforced by two layers of unidirectional composite material of thickness te = 5 mm. The section is subjected to an axial force N = 500 kN. The Young's moduli for the aluminum and unidirectional composite are Ea = 73 GPa and Ec = 140 GPa, respectively. (a) Compute the axial stiffness for this structure. (b) Compute the maximum axial stress in both the aluminum and composite layers. b h The following figure depicts an aluminum / beam of height h = 0.25 m, width b= 0.2 m, flange thickness ta = 16 mm, and web thickness tw = 12 mm.
