Textbook Question
Chapter 9, Problem 71P
As part of the 1976 bicentennial celebration, an enterprising group hung a giant American flag 194 ft high and 367 ft wide from the suspension cables of the Verrazano Narrows Bridge. They apparently were reluctant to make holes in the flag to alleviate the wind force, and hence they effectively had a flat plate normal to the flow. The flag tore loose from its mountings when the wind speed reached 10 mph. Estimate the wind force acting on the flag at this wind speed.
Should they have been surprised that the flag blew down?
