So what, exactly, goes into ski jumping — and how the heck do the jumpers manage to land without killing themselves? Read on for a primer:. Ski jumping began in Norway in the s and was one of the original Olympic sports. Male ski jumpers have been competing in the Olympics since the very first Winter Games in Women, however, were not allowed until the Games in Sochi, following a years-long battle that included a discrimination lawsuit.
Though ski jumping has largely been popular with European audiences, it gained some notoriety in the United States in the s, when the horrific wipeout of ski jumper Vinko Bogataj was used in conjunction with the phrase "the agony of defeat" in the opening montage of "ABC's Wide World of Sports.
Balance, flexibility and an understanding of aerodynamics are crucial. Ski jumpers begin by edging themselves onto a bar at the top of a steep ramp, known as the in-run, before pushing off.
They zoom down the ramp with their skis fixed into ice-filled grooves, their bodies tucked into a low crouch and their arms behind them to maximize speed.
When they reach the end of the ramp, they have a split second to transition into flight mode, using their legs to launch themselves up and forward. The athletes then lean over so they are nearly parallel to their skis, keeping their bodies still to minimize wind resistance. They fly for a few seconds before landing, ideally, with one foot in front of the other. Although jumpers look like they're soaring terrifyingly high in the air, they follow the curve of the hill and thus are only 3 to 5 meters 10 to 15 feet above the ground.
That's why jumpers usually land without shattering their legs — the impact is not particularly severe. As for distance, the world record is held by Austrian Stefan Kraft, who jumped Hot wax is dripped on top of the plastic and scraped smooth to minimize friction.
Modern ski jump in-runs are equipped with ceramic tracks with an integrated cooling system to keep a stable mm-thick ice layer for the jumpers. However, snow conditions and temperature dictate use of different waxes to minimize friction.
There is specific wax for cold weather, warm weather, and even wax designed for storingskis during the off-season. The second section of ski jumping is the table, or takeoff. In fact, the ski jump has about a This means that for ski jumpers to maximize distance of flight, they actually extend from their aerodynamic crouch and jump instead of sliding off the end of the ramp.
Timing, strength, and body position on takeoff are key to a successful jump. The third section of ski jumping, and its most iconic, is flight. During flight, ski jumpers harness the physics of flying like a glider that does not have an engine.
This means in order for ski jumpers to fly, they must use the momentum gained on the ramp and control aerodynamic forces. While in flight, they have three main forces acting on them: lift, drag, and weight. Lift acts perpendicular to airflow. As the air hits horizontally in the face of ski jumpers, lift pushes them up in the air and allows them to soar farther down the hill. Unlike the ramp section where ski jumpers try to minimize body surface area hitting the air, during flight section the goal is to use their flat body and skis to push against the air.
The V flying position is important to increase distance. The skis are wider and longer than alpine and cross-country skis. Ski jumpers wear suits that are spongy microfiber that have a regulated amount of air permeability and must be no more than 2 cm. Sometimes ski jumpers will move their arms and hands to realign their flight path and attempt to stay airborne longer. Weight is the force generated by gravitational attraction toward Earth.
Ski jumpers have learned that lighter jumpers fly farther than heavier ones. Ski jumping skis are also very light, weighing only around 7. The final force ski jumpers contend with is drag. Just like during the ramp section, drag slows ski jumpers in the air. Drag is an unopposed force that quickly slows ski jumpers down. Ski jumpers complete their mastery of physics in the final section, the landing. The landing on which the ski jumpers are judged requires them to move from their V flying shape to skis parallel, one foot slightly ahead, and no more than two ski widths in between.

When ski jumpers launch into the air, they sometimes travel over feet, or the length of about nine school buses or 3.
