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 walkway (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.

Explanation / Answer

P2 = w/2

T2 = P2 = w/2

P3 = T3

T3 = T2

Thus, P3 = T2 = w/2

-w -2P3 + 2P1 = 0

P1 = (w/2) + P3 = (w/2) + (w/2) = w

ANS:

P1 = w

P2 = P3 = w/2

T1 = w

T2 = T3 = w/2
