Steeplechase Water Jump

File: April 15, 2023

 

The steeplechase event requires a combination of speed, endurance, and jumping ability, as athletes must clear the barriers while maintaining their pace and negotiating the water jump. The rules and specifications for the steeplechase event are set by the International Association of Athletics Federations the governing body for the sport of athletics (track and field) worldwide; with minor adaptations by the NCAA for intercollegiate competition.

The steeplechase is a distance race with barriers and a water pit that athletes must clear during the race.  According to the NCAA Track and Field and Cross Country rulebook, the standards for the steeplechase water jump are as follows:

  1. Length: The water pit must be at least 3.66 meters (12 feet) long.
  2. Width: The water pit must be at least 3.66 meters (12 feet) wide.
  3. Depth: The water pit must have a minimum depth of 0.7 meters (2 feet 4 inches) and a maximum depth of 0.9 meters (2 feet 11 inches).
  4. Slope: The slope of the water pit must not exceed 1:5, meaning that for every 5 meters in length, the water pit can rise by no more than 1 meter in height.
  5. Barrier: The water pit must be preceded by a solid barrier that is 91.4 cm (3 feet) high. Athletes are required to clear this barrier before landing in the water pit.

These standards may be subject to change and may vary depending on the specific NCAA division (Division I, Division II, or Division III) and other factors such as venue requirements. Therefore, it’s always best to refer to the official NCAA rules and regulations for the most up-to-date and accurate information on the steeplechase water jump standards in NCAA competitions.

ASTM F 2157-09 (2018) Standard Specification for Synthetic Surfaced Running Tracks
This specification establishes the minimum performance requirements and classification when tested in accordance with the procedures outlined within this specification. All documents referencing this specification must include classification required.

ASTM F 2569-11 Standard Test Method for Evaluating the Force Reduction Properties of Surfaces for Athletic Use
This test method covers the quantitative measurement and normalization of impact forces generated through a mechanical impact test on an athletic surface. The impact forces simulated in this test method are intended to represent those produced by lower extremities of an athlete during landing events on sport or athletic surfaces.

ASTM F 2949-12 Standard Specification for Pole Vault Box Collars
This specification covers minimum requirements of size, physical characteristics of materials, standard testing procedures, labeling and identification of pole vault box collars.

ASTM F 1162/F1162M-18 Standard Specification for Pole Vault Landing Systems
This specification covers minimum requirements of size, physical characteristics of materials, standard testing procedures, labeling and identification of pole vault landing systems.

ASTM F 2270-12 (2018) Standard Guide for Construction and Maintenance of Warning Track Areas on Sports Fields
This guide covers techniques that are appropriate for the construction and maintenance of warning track areas on sports fields. This guide provides guidance for the selection of materials, such as soil and sand for use in constructing or reconditioning warning track areas and for selection of management practices that will maintain a safe and functioning warning track.

Since so much of what we do in standards setting is built upon a foundation of a shared understanding and agreement of the meaning of words (no less so than in technical standard setting) that time is well spent reflecting upon the origin of the nouns and verbs of that we use every day.   Best practice cannot be discovered, much less promulgated, without its understanding secured with common language.

After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play.For almost all athletic facilities,  the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next colloquium on Sport facility codes and standards  We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

“Gelukkige Koningsdag!” Stamppot

Stamppot is a Dutch comfort food known for its simplicity and versatility. It combines mashed potatoes with various vegetables, typically leafy greens like kale (boerenkool), endive (andijvie), or sauerkraut (zuurkool), and often includes bacon or sausage.

The name “stamppot” comes from the Dutch words “stampen” (to mash) and “pot” (pot). The dish is prepared by mashing the boiled potatoes and vegetables together in a single pot. The result is a  slightly chunky mixture of mashed potatoes and vegetables.

There are many variations of stamppot, depending on the vegetables used. The most common types include boerenkool stamppot (kale stamppot), andijvie stamppot (endive stamppot), and zuurkool stamppot (sauerkraut stamppot). Each variation has its own distinct flavor and texture.

Stamppot runs deep in the Netherlands and is considered a staple of Dutch cuisine. It’s a dish that brings people together, especially during the traditional “Hutspot Day” (Hutspotfeest) celebrations in some regions.

“Dutch Student Stew” also known as “Hutspot” in Dutch. It’s a traditional Dutch dish that consists of mashed potatoes, carrots, and onions, often flavored with salt, pepper, and sometimes bacon. It’s a hearty and simple comfort food that has been popular in the Netherlands for many years. The name “Dutch Student Stew” might be a colloquial or humorous reference to the fact that it’s an easy and inexpensive dish to prepare, making it suitable for students or anyone on a budget.

Stray Voltage: Sources and Solutions

Truman C. Surbrook – Norman D. Reese – Angela M. Kehrle

 

Abstract.  Stray voltage is caused by voltage drop and ground faults and may have its origin on the primary electrical distribution system or on the customer’s secondary electrical system. The rms value of the neutral-to-earth voltage along a primary distribution line may be at a value of zero some distance from the substation depending on the condition of the conductor resistances, grounding resistances, and the amount of load. Neutral-to-earth resistance is not the cause of stray voltage; however, the value of this resistance to earth at a particular location will affect the level of stray voltage. A four-wire single-phase feeder system supplying farm buildings from a single metering point is effective in preventing on-farm secondary neutral voltage drop, provided the four-wire system is extended to all farm loads, and provided no high-magnitude ground faults are present. Isolation of the primary and secondary neutral systems at the distribution transformer is effective in preventing off-farm sources from entering the customer’s system. This separation may be accomplished using a number of commercially available devices.
