Hoover Dam Is 660 Feet Thick Where Water Pushes Hardest

Hoover Dam carries water pressure through its own weight and a curved wall that sends compression into the canyon cliffs. Follow the force to understand why the curve alone cannot explain how the dam holds. Then see how interlocking concrete blocks and embedded cooling pipes avoided the cooling problem of a single continuous pour. Learn to distinguish the water's pressure from the lake's storage capacity, and how the dam carries its load from how its concrete was placed and cooled.
