Engineering failures occur when a design, structure, or system does not perform as intended, leading to accidents, damage, or loss. These failures can result from various factors, including poor design, material defects, or inadequate testing. Notable examples include the collapse of the Tacoma Narrows Bridge in 1940 and the Challenger Space Shuttle disaster in 1986, both of which highlight the importance of thorough engineering practices. Such failures often lead to significant consequences, including financial loss, injury, or loss of life. They serve as critical learning opportunities for engineers and organizations, prompting improvements in safety standards, design protocols, and regulatory measures to prevent future incidents.
