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.
is the shear stress, measured in newtons per square meter (N/m2, also called pascals, Pa), while
—called a reduced tension—is the resultant tension of the material.
Finds application in calculating the span width of the bridges, their beam cross-sections, etc.
