A 4-stroke internal combustion engine was used to power a Global GT1 race car. Although commonly used to power Global Class race cars, the engine was not designed for this application. The engine was acquired by the University of Derby; after which it was rebuilt. It was then mounted transversely as a stressed member of the GT1 chassis. Throughout its track life, the engine was run at very high speeds, exceeding 11,000 revolutions per minute (RPM). After the engine rebuild, the car had run for around 50 race hours before failing. During a race the engine failed catastrophically with a sudden loss of power. Upon dismantling the engine, a connecting rod was found to have failed along with one of its bolts and its slip bearings. Fig. 1a shows a typical connecting rod with key features highlighted and Fig. 1b shows an intact connecting rod next to the failed connecting rod. Connecting rods undergo cyclical tensile and compressive loading during the combustion cycle, suggesting fatigue could be the cause of a failure. At the point of failure, the brake and throttle were being applied, increasing the magnitude of these forces. Please analyze to find the mechanism of the failure of
