Problem 1(15 Points)
For the long, thin beam with pinned ends displaced as shown below, determine the displacement field, \( u(x)\), using the Rayleigh-Ritz method. Assume a fourth-order polynomial as a trial function. Feel free to use software (i.e., Matlab, Mathematica) to decrease the potential for integration/algebra errors.
