Abstract:
An apparatus for use on a snow surface, comprising:a nose, a tail, and a body connecting said nose and tail, said body including, a top surface, a bottom surface, a front half, and a rear half, said top and bottom surfaces separated by a thickness; said body further including a first mounting zone located in said front half and adapted to receive one foot of a rider of said apparatus and a second mounting zone located in said rear half and adapted to receive the other foot of said rider; said body further including a plurality of cross-sectional portions; and a first static loading condition comprising a first downward load applied to said first mounting zone, a second downward load applied to said second mounting zone, and an upward load applied along said bottom surface; wherein the value of the following expression is substantially constant when applied to each of said plurality of cross-sectional portions, respectively, and said first static loading condition is applied to said body: M/EI â€ƒwherein: E is the modulus of elasticity of said body for said respective cross-sectional portion; I is the area moment of inertia for said respective cross-sectional portion; and M is the bending moment acting on said respective cross-sectional portion under said first static loading condition.
