Round 5: Tossup 11

The compressive force on the bottom of a tapered structure reduces the effective strength of this phenomenon in the Resal effect. Mindlin plate theory introduces a correction factor kappa to ensure the internal energy from this phenomenon is correct. The Tresca criterion sets an upper bound on the strength of this phenomenon. A classic method to calculate beam deflection involves first plotting this phenomenon and then integrating that plot to produce a (*) bending moment diagram. When this phenomenon is ignored, Timoshenko beam theory reduces to Euler–Bernoulli beam theory. The off-diagonal components of the Cauchy stress tensor represent the stress named for this phenomenon, (10[1])denoted tau. For 10 points, normal forces are contrasted with forces from what phenomenon, which are parallel to a material’s cross-section? ■END■ (10[1]0[1])
