Question
For 10 points each, answer the following about determining the deflection of a beam:
[10e] A beam’s second derivative of deflection with respect to position equals negative bending moment over I times a quantity named for this scientist. That “modulus” named for this scientist equals stress over strain.
ANSWER: Thomas Young [accept Young’s modulus]
[10m] To draw a bending moment diagram, one integrates the beam’s value of this quantity across its whole length. This quantity, symbolized tau, represents force applied parallel to a material’s surface.
ANSWER: shear force [or shear stress; prompt on V]
[10h] To determine the critical buckling load, one must analyze the beam’s slenderness ratio, calculated as length over this quantity. This quantity equals the square root of I over A.
ANSWER: least radius of gyration [or gyradius; prompt on r or k]
