In most simple expression and commonly in use it looks like this: σ r e d = ( σ 2 ) + 3 ( τ 2 ) {\displaystyle \sigma _{red}={\sqrt {({\sigma }^{2})+3({\tau }^{2})}}} where σ {\displaystyle \sigma } is the tensile stress, and τ {\displaystyle \tau } is the shear stress, measured in newtons per square meter (N/m2, also called pascals, Pa), while σ r e d {\displaystyle \sigma _{red}} —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. == See also == Yield surface Stress–energy tensor Tensile stress von Mises yield criterion == References == - [[History and Theory/Temple Architecture/Stone Temples of India/pillars]] - [[Environmental Design/Life Cycle Assessment]] - [[Urban and Planning/Public Space]] - [[Digital Architecture/Computational Design]] - [[Digital Architecture/ePractice/BIM and Digital Modeling]] - [[Building Construction/Construction & Materials/Building Material/Natural Stone]] - [[Design/Architectural Design/Design Theory]] - [[Building Construction/Construction & Materials/Building Material/Timber and Wood Products]] - [[Building Construction/Construction & Materials/Building Material]] - [[History and Theory]]
