Discussion Overview
The discussion centers on calculating the force experienced by a skydiver during deceleration from terminal velocity to a lower speed. It involves considerations of deceleration rates and the effects of equipment design on the deceleration experience.
Discussion Character
- Technical explanation, Conceptual clarification, Debate/contested
Main Points Raised
- One participant inquires about the calculation of force during deceleration from approximately 120 mph to 30 mph over one second.
- Another participant converts the speeds to feet per second, calculating a deceleration of 132 ft/sec², which they equate to about 4 g's.
- A subsequent post notes that this calculation assumes constant deceleration, suggesting that equipment manufacturers aim for this type of deceleration.
- Another participant introduces the idea that there is an effort to reduce jerk, indicating that initial deceleration may not be as high as the maximum deceleration experienced.
Areas of Agreement / Disagreement
Participants present differing views on the nature of deceleration, with some focusing on constant deceleration and others highlighting the importance of reducing jerk. No consensus is reached on the best approach to calculate the force involved.
Contextual Notes
The discussion does not resolve the assumptions regarding the nature of deceleration or the specific design considerations of skydiving equipment that may affect the calculations.
