Step 1: Calculate the cross-sectional area and moment of inertia for each arm. The arms are approximated as hollow steel tubes. We will use Young's modulus for steel, E = 29 × 10^6 psi. For arm AD: Outer diameter D_1 = 10 in. Inner diameter d_1 = 9.5 in. Length L_1 = 100 in. Damping coefficient c_1 = 0.4 lb-s/in. (assuming standard units for damping) Cross-sectional area A_1: A_1 = 4 ✂️ _That answer was long and got cut off. Reply continue and I'll finish it._
