A vertical AISI 1045 cold drawn steel bar ABC is supported at its upper end and loaded by a static forceP₁ = 2250 lbat its lower end as shown in Figure 1. A horizontal beam BDE is pinned to the vertical barat point B and supported at point D. The beam carries a static force P₂ = 5800 lb at end E. The upperpart of the vertical bar (segment AB) has length L₁ = 2.0 in and diameter d₁ = 0.564 in; the lower part of the vertical bar (segment BC) has length L₂ = 3.0 in and diameter d₂ = 0.451 in. The left and right hand parts of beam BDE have lengths a = 2.8 in and b = 2.5 in, respectively. The fillets and pinholes on bar ABC can be neglected. Analyze the applied stresses, strains, principle stresses, Von Mises stresses, and factor of safety of segments AB and BC, and the vertical displacement at point C. using both theoretical equations and-computationally. Compare and discuss the results of your analyses. Suggest relevant design changes-based on your analyses. Include figures and tables as necessary to support and communicate your findings. Make sure to clearly discuss any relevant assumptions and explain the details of your computational analysis setup.

Given: The WT4 x 15.5 member shown is connected to a gusset plate with fillet welds as indicated. The yield stress of the T-section is Fy = 50 ksi. Find: The effective net area of the T-section.
