Within the reinforced concrete construction industry, it’s widely known that a 1/2-inch-diameter post-tensioning tendon can hold around 27 kips (120 kN) when in tension. 1 kip equals 1,000 pounds-force and 1 pound-force equals the gravitational force exerted on a mass of 1 pound on Earth’s surface.
Fair enough — but what can that tendon hold:
12,258,000 U.S Dollar bills
109,367 Apple iPhone 5s smartphones
67,500 Rubik Cubes
43,200 bags of Lays Classic potato chips (10 oz.)
4,376 Sony Playstation 4 sets
3,375 Harry Potter paperback box sets (shipped weight of books 1-7)
200 Fish Tanks (including a few fish and flora inside 10 gallon of water)
So, it seems, the only thing on the above list that can beat a 1/2-inch-diameter post-tensioning tendon would be something like this:
It’s fun to make something technical and serious interesting. And this qualification certainly justifies recognition of the Amsysco Post-Tensioning Blog as a worthy entry in the 2015 Best Construction Blog Competition.
