Question

1.Determine the reactions at A and D. (in kips)

Two cylindrical rods, AC made of aluminum and CD made of steel, are joined at Cand restrained by rigid supports at A and D. It is given that Ea= 10.4 x 106 psi, Es= 29 106 psi, and P = 34 kips. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 18 in.|410 in.- 10 in. B > • 14 kips 14-in. diameter 1-in. diameter
