# QUESTION
The bridge's collapse had a lasting effect on science and engineering. In many physics textbooks, the event is presented as an example of elementary forced resonance; the bridge collapsed because normal speed winds produced aeroelastic flutter that matched the bridge's natural frequency. The collapse boosted research into bridge aerodynamics-aeroelastics, which has influenced the designs of all later long-span bridges.

# QUESTION
Formal race meetings began to be instigated too. It is believed that the first occurrence of a trophy being presented to the winner of a race was in 1512 by organisers of a fair in Chester and was a small wooden ball decorated with flowers. Meanwhile, the oldest horse race still in existence, the Kiplingcotes Derby was first run in 1519. The Carlisle Bells, reputedly the oldest sporting trophy in the world, were first competed for in the 16th century, in a race that still bears their name. One of the bells is inscribed "The sweftes horse thes bel tak" ("The swiftest horse takes this bell").

# QUESTION
The American System was an economic plan that played a prominent role in American policy during the first half of the 19th century. Rooted in the "American School" ideas of Alexander Hamilton, the plan "consisted of three mutually reinforcing parts: a tariff to protect and promote American industry; a national bank to foster commerce; and federal subsidies for roads, canals, and other' internal improvements' to develop profitable markets for agriculture". Congressman Henry Clay was the plan's foremost proponent and the first to refer to it as the "American System".
