The World's Largest Deadweight Machine is Getting a Bath
The National Institute of Standards and Technology (NIST) is in the process of cleaning, restoring and recalibrating its 4.45-million Newton deadweight machine. Known to be the largest in the world, that's equivalent to one million pounds-force. This is the first time in 50 years the NIST has
