A cross-sectional view is shown of the skyways in the Kansas City Hyatt Regency hotel in their as-constructed form, along with the forces acting on the nuts and washers that contact the two walkways (Figure P4.25).

(a) Draw free body diagrams of the upper and lower walkways, including the weight w that acts on each.

(b) Determine the forces P₁, P₂, and P₃ between the washers and the walkways, and the tensions T₁, T₂, and T₃ in the hanger rods.

(c) The skyways’ collapse was associated with an excessive force P₁. How does the value you calculated here compare with the value of P₁ obtained in Problem P4.24?
