Huber's equation, first derived by a Polish engineer Tytus Maksymilian Huber, is a basic formula in elastic material tension calculations, an equivalent of the equation of state, but applying to solids. In most simple expression and commonly in use it looks like this:
where is the tensile stress, and is the shear stress, measured in newtons per square meter (N/m<sup>2</sup>, also called pascals, Pa), while âÂÂcalled a reduced tensionâÂÂis the resultant tension of the material.
Finds application in calculating the span width of the bridges, their beam cross-sections, etc.
