James Warren and Willoughby Monzani's Piece of Wood

Origin
James Warren and Willoughby Monzani were engineers who patented the Warren-style truss bridge and girder design. This bridge design is mainly constructed by equilateral triangles which can carry both tension and compression. The first suspension bridge to utilize a Warren truss in its design was the Manhattan Bridge in New York City. This configuration was also used in the wing designs of early biplanes.

Effects
This wooden plank allows those who touch it to talk to buildings and other structures. It is constantly squeaking and groaning, as if someone were trying to bend a large girder or walking down a very squeaky wooden stairway.
