TL;DR

A physical scientist manages a one-of-a-kind machine that calibrates enormous masses for accurate force measurement.

Transcript

An apple weighs about 1 newton, the world record for jet engine thrust is 570,000 newtons. And the Saturn V rocket that launched people to the moon had a thrust of 33,360,000 newtons But how can we measure forces this big accurately? Well, we need to ask this guy. Hi my name is Rick Seifarth I'm a physical scientist in the Mass and Force Group. Am ... Read More
