In this paper, numerical
solution of a boundary value problem for a fourth-order ordinary differential
equation, known as the Euler-Bernoulli beam equation, is presented. The related
equation is used extensively in engineering areas such as huge buildings, long
bridges across big rivers, planes and cars. The approximate solution of the
problem considered is obtained by using the Galerkin method with basis
functions that satisfy the boundary conditions given. The accuracy of the
proposed method is given through two numerical examples with the help of Maple^®program.
