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.
In the engineering world, we deal with holding dead and service loads as opposed to “things.” Here is list of real-life “things” that 1 PT tendon can 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)
89 GE Side-by-Side 21.9 cu.ft Refrigerators
9 Toyota Corolla (2014 curb weight)
5 Tesla Model S (2014 curb weight)
1 Dallas Cowboys endzone Jumbotron (a sideline jumbrotron needs 7 PT tendons)
