Euler–Bernoulli beam theory (also known as engineer's beam theory or classical beam theory) is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams. It covers the case corresponding to small deflections of a beam that is … See more Prevailing consensus is that Galileo Galilei made the first attempts at developing a theory of beams, but recent studies argue that Leonardo da Vinci was the first to make the crucial observations. Da Vinci lacked Hooke's law See more The dynamic beam equation is the Euler–Lagrange equation for the following action The first term represents the kinetic energy where $${\displaystyle \mu }$$ is the mass per unit … See more Besides deflection, the beam equation describes forces and moments and can thus be used to describe stresses. For this reason, the … See more Applied loads may be represented either through boundary conditions or through the function $${\displaystyle q(x,t)}$$ which represents an external distributed load. Using distributed loading is often favorable for simplicity. Boundary conditions are, however, often … See more The Euler–Bernoulli equation describes the relationship between the beam's deflection and the applied load: The curve $${\displaystyle w(x)}$$ describes the deflection of the beam in the $${\displaystyle z}$$ direction at some position See more The beam equation contains a fourth-order derivative in $${\displaystyle x}$$. To find a unique solution $${\displaystyle w(x,t)}$$ we need four … See more Three-point bending The three-point bending test is a classical experiment in mechanics.
