    Calculation G-force
Click For Summary
SUMMARY

The discussion focuses on calculating g-forces experienced by a ski jumper during an innrun with a 40-meter radius curve, transitioning from a 37-degree angle to a 9-degree angle. At a speed of 93 km/h at the lowest point, the maximum g-force calculated is 2.7 G, which consists of 1.7 G from centripetal acceleration and 1 G from gravity. The inquiry also addresses whether changing the curve from 180 degrees to 152 degrees would affect the g-forces experienced, concluding that the angle does not significantly impact the forces at play.

PREREQUISITES
  • Understanding of centripetal acceleration
  • Basic knowledge of g-force calculations
  • Familiarity with physics concepts related to motion and gravity
  • Ability to interpret speed and angle measurements in a physical context
NEXT STEPS
  • Research the physics of centripetal acceleration in circular motion
  • Learn about g-force calculations in sports dynamics
  • Explore the effects of different angles on g-forces in skiing
  • Investigate the impact of speed variations on g-force experiences
USEFUL FOR

Athletes, coaches, and sports scientists interested in understanding the physical forces acting on ski jumpers during performance, as well as engineers and physicists studying motion dynamics in sports.

Hello, I´m a skijumper and wondering the amount of g-forces I am put through in the innrun.
So this is the data:

Radius 40 meter
Angel before the curve 37 degrees
Angel after the curve 9 degrees
Speed 93 km/h
The speed at the start of the curve is probably 85 km/h and 93 km/h at the end.

Can someone calculate the amount of g-forces please?

Would the amount of g-forces been different if you would have gone from 180 degrees to 152 degrees. Or does the angel of where you are have nothing to say?

Thank you.

Highest g-forces will always be at the very bottom of the curve, because that's where Earth's gravity adds directly with the force due to centripetal acceleration, as well as being the point of highest velocity.

Assuming that 93km/h is good estimate for speed at the lowest point (the 9° after that shouldn't make a big difference) you'd be pulling max of 2.7 G. (1.7 from curvature + 1 from gravity).
 
Thank you
