Solved: A copper strip (Ec 5 105 GPa) and an aluminum strip (Ea 5 75 GPa) are bonded
Chapter 11, Problem 11.33(choose chapter or problem)
A copper strip \(\left(E_{c}=105 \mathrm{\ GPa}\right)\) and an aluminum strip \(\left(E_{a}=75 \mathrm{\ GPa}\right)\) are bonded together to form the composite bar shown. Knowing that the bar is bent about a horizontal axis by a couple of moment \(35 \mathrm{\ N} \cdot \mathrm{m}\), determine the maximum stress in (a) the aluminum strip, (b) the copper strip.
