Discussion Overview

The discussion revolves around calculating the pressure exerted on the hooves of jumping stilts and the ground during use. Participants explore the implications of this pressure for selecting an appropriate indoor venue, particularly concerning the structural integrity of the floor.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the method to calculate the pressure on the hooves and ground when using jumping stilts, providing specific measurements for surface area and contact time.
  • Another participant questions whether the focus should be on pressure or force, suggesting that understanding the force may be more relevant for assessing floor loading limits.
  • A third participant shares a video link, expressing surprise at the activity, which may imply a need for further exploration of the forces involved.
  • A later reply confirms that the floor is a sprung floor and notes that there is no loading limit, but emphasizes the need to demonstrate that the downward force will not damage underfloor pipes.
  • Participants discuss the relationship between user experience and jumping height, indicating that skilled users can achieve greater heights than inexperienced ones.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether pressure or force is the more critical measure to consider. There are differing views on the implications of jumping height and the potential impact on the floor.

Contextual Notes

There are unresolved assumptions regarding the calculations needed to determine pressure or force, and the specifics of how the jumping stilts interact with the ground during use. The discussion also highlights the variability in jumping performance based on user experience.

Hi there

I am using a pair of pro-jump jumping stilts (spring loaded)

We are looking for an indoor hall for when it rains.
Does anyone know how to work out the approx. pressure on the hooves/ground when jumping?

The surface area of the bottom of the stilts is 5935.472mm^2 (length - 101.6mm, width - 58.42mm).

The time the hooves are in contact with the floor is 2 seconds.

The highest you can jump in them is 6 foot.

Is it really the pressure that you want, or the force? Is there a limit for the loading allowed on the floor in the indoor hall, for example, and that's why you need to know?

And are you serious about the height being 6 feet :bugeye: That's how high the bottoms of the spring-loaded stilts get off the floor?
 
The force on the ground would be very helpful yes.

The floor is a sprung floor.
As far as I know there is no loading limit on the floor, broastcasts with full live audiences have been held in there for example.
There is however underfloor pipes and the owner wishes for us to prove that the downward force is not going to damage them before using the hall.

The video above shows the little effort put into jumping therefore I'm under the assumption that the majority of the forces are absorbed and given back by the spring.

The max height for the correct weight category is 6 feet yes.
Unexperienced users using heigher weight categories tend not to get much air, however experienced users with practised technique can get up to 8 (skill level very dependent).

Many thanks for your time once again with this matter
