Connecting rods are subject to high levels of stress and heat during operation, which means they must be designed and manufactured to withstand these conditions. They are often made from high-strength steel or aluminum alloys and are designed using advanced computer-aided engineering (CAE) software.
In addition to their performance characteristics, connecting rods also play a crucial role in the engine's longevity. A failure of the connecting rod can result in catastrophic engine damage, which can be both costly and dangerous.
