Packet 5: Tossup 17

Heinrich Müller-Breslau developed a method for computing the extent of this process that creates a “conjugate” structure subject to a set of dual equations. Mohr’s theorems are used to derive Clapeyron’s theorem for systems where this process occurs thrice. A universal testing machine is used to perform “three-point” and “four-point” (10[1])measurements for materials that undergo this process. Shear force (-5[1])and a quantity for this process (10[1])are plotted on a pair of diagrams (10[1])that track influence lines. (10[2])In static systems, the fourth spatial derivative of a quantity for this process is proportional to the applied load. (10[1])In Euler–Bernoulli (10[1])theory, (10[1]-5[1])structures (10[1])undergo (10[1])this type (-5[1])of motion elastically in response to (-5[1])applying (-5[2])a transverse load. (10[2]-5[1])For 10 points, name this motion in which a beam (-5[1])is unaligned from its axis, (10[2])causing it to curve. ■END■ (10[8]0[3])

ANSWER: bending [accept flexing or deflection; accept bending moment; prompt on elastic or plastic deformation; prompt on curving until “curve”]
