The ratio of the finite difference of function values at two points to the distance between those points gives an approximation to a derivative of the function. True False Elementary theory accurately approximates the cross-section warping of elliptical bars subjected to torsion loading. O True O False PES For long, slender columns, the critical stress for elastic buckling may be increased by using stiffer materials (increased E), but not by using a stronger material (increased Ou). True False Intermediate length columns fail by inelastic buckling at stress levels exceeding the ultimate strength O Truc O False It is generally ok to neglect shear in calculating deflection due to transverse loading of the beam is "slender" because the contribution is small. O True False There are no shear stresses on the planes on which principal stresses act. O True O False
