Jack Stands in North American Rally - A Design Proposal
Bibliographic record
Abstract
<div class="section abstract"><div class="htmlview paragraph">ABSTRACT</div><div class="htmlview paragraph">Rally cars are among the most technologically advanced and complex race cars, with intercooled forced induction, adaptive all wheel drive and high-feature engine management being standard features for open class racers in all major North American Rally series. This high level of technology and complexity places additional burden on the service crews and mechanics charged with the task of preparing and repairing the vehicles during the competition. As such, it is of great importance that the brief service stops (thirty minutes per FIA regulation 17.2.2 [2008]) be executed as efficiently as possible.</div><div class="htmlview paragraph">In the pursuit of valuable seconds, rally mechanics have shown a great deal of ingenuity, creating tools and procedures which are unique to the sport. One such innovation is the peg-style jack stand. As with a typical jack stand, these devices are intended to hold the car suspended above the ground at a height allowing mobility of the mechanics under the vehicle to maneuver large components such as transmissions and differentials. It is popular practice for teams to fabricate customized jack stands, without following regulations set forth by any North American sanctioning body. The jack stands used vary from being low-quality imported purchase pieces, to highly engineered fabrications. While injuries due to jack stand failure have not been a major problem to date, it is prudent to examine the situation and explore the possibility of implementing regulations which govern these tools.</div><div class="htmlview paragraph">The sport of Rally places great importance on the safety of the drivers and co-drivers, with exhaustive regulations regarding systems such as roll cages, helmets, safety belts and fire suppression, yet there are few regulations in place to ensure the safety of the service crews. Mechanics regularly trust their lives to the jack stands which suspend the cars above them.</div><div class="htmlview paragraph">The following paper will explore this issue through the analysis of some exemplary, popular designs of peg-style jack stands. An alternative design, with increased strength and durability as well as reduced sensitivity to fabrication errors, ground conditions, and user errors will also be explored. This proposed design is presented with a mind towards the implementation of a regulation-mandated standardized design.</div></div>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
