Round 1: Tossup 8

Saint-Venants’ principle states that this quantity becomes uniform a sufficient distance from its originating load. Imparting “residual” values of this quantity is used to strengthen brittle materials such as glass or concrete. This quantity is fully described by a tensor named for Augustin-Louis Cauchy (“KOH-shee”). Like pressure, this quantity (15[1])can be measured in (*) pascals. When (-5[1])this quantity (10[1]-5[1])acts parallel to a material’s cross section, it is called “shear.” (-5[3])This quantity (-5[2])is the y-axis of a curve whose slope equals Young’s modulus. For 10 points, name this quantity that measures internal forces during deformation, contrasted (10[1])with strain. (10[1])■END■ (10[4]0[5])
