The assembly consists of a steel and an aluminum bar, each of which is 1 in. thick, fixed at its ends \(A\) and \(B\), and pin connected to the rigid short link \(C D\). If a horizontal force of \(80 \mathrm{lb}\) is applied to the link as shown, determine the moments created at \(A\) and \(B . E_{\mathrm{st}}=29\left(10^{3}\right) \mathrm{ksi}, E_{\mathrm{al}}=10\left(10^{3}\right) \mathrm{ksi}\).
