Two cylindrical rods, \( A C \) made of aluminum and \( C D \) made of steel, are joined at \( C \) and restrained by rigid supports at \( A \) and \( D \). It is given that \( E_{a}=10.4 \times 10^{6} \mathrm{psi}, E_{S}=29 \times 10^{6} \mathrm{psi} \), and \( \mathbf{P}=26 \mathrm{kips} \). NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the reactions at \( A \) and \( D \). The reaction at \( A \) is \( \quad \) kips \( \leftarrow \). The reaction at \( D \) is kips \( \leftarrow . \)
