WebSep 11, 2016 · According to the chart, in a 110 mph zone, walls experience about 20 lb. per sq. ft., and closer to 30 lb. per sq. ft. at the outside corners (where the wind accelerates to get around the building, like air over an airplane wing). Both positive and negative pressures are listed. A steep roof like ours has similar wind pressure numbers to the walls. WebThis remarkable fact is a consequence of Newton's third law. Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another ...
