Homework 2, problem 1 Solve for the approximate deflection of a simply-supported prestressed cable with uniform static distributed load using the Galerkin method. Take as the trial function N 1 ( x ) = x 3 ( x - L ) 3 , and set the test function to coincide with the trial function, η 1 = N 1 . (a) Compare the midpoint deflection computed analytically and approximately. (b) Compute and plot the balance residual. (c) Compute the reactions at the pins from the approximate solution. Homework 2, problem 2 Solve for the approximate deflection of a simply-supported prestressed cable with uniform static distributed load using the Galerkin method. Model just one half of the problem using a symmetry plane. Take as the trial function N 1 ( x ) = 2 x/L ( x = 0 is the location of the pin support at the left-hand side end of the cable), and set the test function to coincide with the trial function, η 1 = N 1 . (a) Compare the midpoint deflection computed analytically and approximately.
