The physics of ski jumping
The Olympian ideal of going faster, jumping further and leaping higher than the opposition is central to competitive sports. Winning or losing in sport is related to a number of factors, and biomechanics, anthropometrics, and aerodynamics play a major role in many sports. This lecture focuses on ski jumping. Performance in ski jumping is determined not only by the motor abilities of the athlete...
متن کاملSki jumping takeoff in a wind tunnel with skis.
The effect of skis on the force-time characteristics of the simulated ski jumping takeoff was examined in a wind tunnel. Takeoff forces were recorded with a force plate installed under the tunnel floor. Signals from the front and rear parts of the force plate were collected separately to examine the anteroposterior balance of the jumpers during the takeoff. Two ski jumpers performed simulated t...
متن کاملFramsticks: Evolved running, swimming, and ski-jumping
1. The first, introductory part is a one-minute sequence showing a simulation of Foraminifera – single-celled eukaryotes that occupy marine benthic and pelagic zones from polar to tropic areas. These organisms have an extraordinary fossil record since Cambrian (about 540 million years ago), which makes them an ideal model organism and a microfossil often used for paleoreconstructions and testin...
متن کاملA note on non-jumping numbers
Let r ≥ 2 be an integer. A real number α ∈ [0, 1) is a jump for r if there exists c > 0 such that for any ǫ > 0 and any integer m, m ≥ r, there exists an integer n0 such that any r-uniform graph with n > n0 vertices and density ≥ α + ǫ contains a subgraph with m vertices and density ≥ α+ c. It follows from a theorem of Erdős and Stone that every α ∈ [0, 1) is a jump for r = 2. Erdős asked wheth...
متن کاملIs It Still Important to Be Light in Ski Jumping?
In ski jumping low body weight development resulted in some serious underweight problems and therefore International Ski Federation (FIS) decided to solve the problem by relating maximum ski length to Body Mass Index (BMI). The present study examined the current relationship between body weight (BMI), ski length and performance (jumping distance) in ski jumping. The computer simulation showed t...
