Behold the stomach-clenching spectacle of the quadruplet cork 1800. The dizzying snowboarding trick–first territory by British Olympian Billy Morgan, above–involves propelling off a ramp into four off-axis flips( called corks) and five full rotates. Merely four parties had already been completed the 1,800 -degree stunt. But this month in Pyeongchang, South Korea, expect to see more attempts as elite wintertime jocks compete in the Olympic debut of Big Air, an contest in which boarders barrel off a 110 -foot-tall ramp to perform apparently impossible throws and twirls. We enlisted physicist John Eric Goff, author of Gold Medal Physic: The Science of Sports, to break the forces at gambling behind the quadruplet cork 1800.
Olympic boarders will accelerate down 240 feet of descent, 39 positions at its steepest, before hurling off the ramp. Speed is key here: Too slow, and they won’t get enough breath to ended four throws. Goff reckons Morgan makes nearly 40 mph at takeoff.

Achieving the quadruplet cork’s difficult combination of flip and revolve requires a simultaneous trunk twisting and abdominal crunch. That speedy change likely makes about 50 foot-pounds of torque, 1,000 seasons the torque it takes to turn your head.
