Prob. 3.3-2. The three-part axially loaded member in Fig. P3.3-2 consists of a tubular segment (1) with outer diameter (d.), = 1.25 in. and inner diameter (d), = 0.875 in., a solid circular rod segment (2) with diameter dy = 1.25 in., and another solid circular rod segment (3) with diameter d 0.875 in. The line of action of each of the three applied loads is along the centroidal axis of the member. (a) Determine the axial stresses ₁, 2, and a, in each of the three respective segments. (b) If L₁ = L₂ = L₁ = 20 in. and E= 30 × 10¹ ksi, what are the nodal displacements ta, c, and up? 0.875 in A 1.25 in. t (2) 3 kips B 4 kips -L₂- P3.3-2 0.875 in. (3) Ly 2 kips D Up
