Modern Marvels: The World's Strongest
Strength... it's a powerful word, but what does it mean? How is it measured? And what makes some materials stronger than others?
In this mesmerizing program, History investigates some of the strongest substances in the world and puts their various forms of strength to the test. In Bowling Green, Ohio, visit the National Tractor Pulling Championship and witness colossal tractors with 12,000-horsepower engines pulling loads upwards of 60,000 pounds. Then, explore the power of tensile strength during a tour of the Puget Sound Rope Factory, where the strongest rope in the world is made. Finally, climb aboard the Morgan Foss for a lesson in how tugboats are able to exert carful control over the massive ships they maneuver.
From diesel engines and polycarbonate plastics to diamonds and spider silk, The World's Strongest is a rare look at everyday applications for some of the toughest stuff on earth.
