Question
. A composite beam, made of aluminum (Al) and magnesium (Mg), has the cross section
shown below. The moduli of elasticity for aluminum and magnesium are EAI
= 70 GPa
and EMg = 45 GPa, respectively. If the allowable flexural stresses (in tension and com-
pression) are All 135 MPa for the aluminum and Mg 120 MPa for the magnesium,
determine the maximum allowable bending moment for the beam.
