The Engineering Secrets of the World's Toughest Beetle

The video explores the unique strength of the diabolical ironclad beetle, which can withstand extreme pressure due to its specialized exoskeleton. This beetle, native to Southern California, has a skeleton that supports 39,000 times its body weight. Its exoskeleton is made of chitin and proteins, with a high protein-to-chitin ratio and cross-links that enhance its strength. The beetle's fused eletra acts like a jigsaw puzzle, distributing pressure across its body. This adaptation allows it to survive being run over by a car. The video also discusses how these natural adaptations can inspire engineering solutions, such as creating stronger, lighter structures without fasteners.
