Sure pinewood derby laws stipulate that solely a particular variety of wheels ought to contact the observe floor through the race. This typically entails configuring the automobile in order that one wheel is barely elevated, minimizing friction. An instance features a automobile the place two wheels roll on the observe whereas the third, on the identical facet, is barely raised.
Adherence to this specification, often achieved by way of cautious axle bending or wheel canting, can improve the automobile’s efficiency. The intent is to scale back the rolling resistance by limiting the factors of contact, thereby growing the automobile’s pace. Traditionally, this method has developed from experimentation aimed toward optimizing automobile dynamics throughout the framework of formally sanctioned competitions.
