Visa mer 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 … Visa mer 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 Visa mer Besides deflection, the beam equation describes forces and moments and can thus be used to describe stresses. For this reason, the Euler–Bernoulli beam equation is widely used in engineering, especially civil and mechanical, to determine the strength (as well as … Visa mer 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, … Visa mer 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 and calculus to complete the theory, … Visa mer The dynamic beam equation is the Euler–Lagrange equation for the following action Visa mer The beam equation contains a fourth-order derivative in $${\displaystyle x}$$. To find a unique solution $${\displaystyle w(x,t)}$$ we need four boundary conditions.
