A chain hoist is attached to the ceiling through three tie rods as shown below. The tie rods are made of coldrolled steel with yield strength σyp and each has an area A. Find the deflection δ at load F1 when the deflections
are elastic in all three rods. When the frame is loaded to F2 (where all three rods become fully plastic), and then
unloaded, find the residual stress σr in the central rod. Figure 11.1 Residual Stress Problem Sketch Material Properties

A = 1 in2 E = 30 x 106 psi = 100 in
Θ = 30° Loading
F1 = 51,961.5 lb
F2 = 81,961.5 lb Note — F1 and F2 values are back-calculated from theoretical relationships. Analysis Assumptions and Modeling Notes
