SOLVED: The composite beam is made of steel (A) bonded to brass (B) and has the cross section shown. If it is subjected to a moment of M=6.5 kN ·m, determine the maximum bending stress in the brass and steel. Also, what is the stress in each material at the seam where they are bonded together? Ebr=100 GPa, Est=200 GPa | Numerade

SOLVED: Problem 1 (10 Points): The composite beam consists of a wood core (Ew = 10 GPa) and two steel plates (Es = 200 GPa). If the allowable bending stress for the wood is Sallow = 20 MPa, and for the steel is Sallow = 150 MPa, determine the maximum moment (My) that can be applied to the beam. The dimension (d) of the cross-section is given in the table below for each student. Hint: transform wood to steel.20 mm 75 mm20 mm
