WebbBeam bending rotation theta is actually the first derivative of the first displacement, while the bean curvature kappa is the second displacement. So we can see that the bending moment, M, is actually related to the beam deformation through the second derivative of the beam deformation. WebbThe first key requirement of statics, that there should be no net thrust across a cross-section in pure bending, was recognized in the eighteenth century; but it was only in 1826 that Navier stated explicitly that as a consequence the neutral axis must pass through the centre of gravity of the cross-section. mary mother of our lord

WebbThe dynamic bending of beams, [8] also known as flexural vibrations of beams, was first investigated by Daniel Bernoulli in the late 18th century. Bernoulli's equation of motion of a vibrating beam tended to overestimate the natural frequencies of beams and was improved marginally by Rayleigh in 1877 by the addition of a mid-plane rotation. http://www.annualreport.psg.fr/j_theory-of-unsymmetrical-bending-of-beams.pdf
