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. (-5[2])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 (-5[1])to Euler–Bernoulli beam theory. The off-diagonal components of the Cauchy stress tensor represent the stress named for this phenomenon, 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[2])
