Question
A 2023 paper by Wen et al. describes how a quantity named for this physicist is octupled for the ovipositors of female Megarhyssa wasps before they lay eggs in wood. For 10 points each:
[10m] Name this physicist who names the longitudinal compression load at which a given slender column buckles. This physicist is the alphabetically-later namesake of a fourth-order ODE relating a beam’s deflection to its applied load.
ANSWER: Leonhard Euler [accept Euler’s critical load or Euler–Bernoulli equation]
[10e] Euler’s critical load is proportional to this quantity for the column, denoted capital I. This rotational analog of mass multiplies angular acceleration to give torque.
ANSWER: moment of inertia [or rotational inertia; or angular mass; or mass moment of inertia; or second moment of mass]
[10h] The bending behavior of the Megarhyssa ovipositor exemplifies this structural design approach coined by Buckminster Fuller, in which compressed components are isolated from each other within a network of pre-tensioned cables.
ANSWER: tensegrity [or tensional integrity or floating compression]
