    The Tacoma Narrows Bridge was designed for a wind speed of 100 miles per hour and a static wind pressure of 30 pounds-force per square foot but unfortunately the bridge failed at a wind speed of less than half and a static wind pressure of one-sixth (Delatte, 2009). This phenomenon raises a big question mark on how this is possible. At first, resonance was suspected to be the main cause of the bridge failure (The New York Times, 1940). After some proper research and thorough investigations by engineers

It lacked the ability to resist the winds but rather swayed and vibrated with the wind direction (Britton, n.d.). Due the harmonic phenomena, the swaying of the bridge worsened (Britton, n.d
