Problems 16.8

For the bar shown in Figure P16–8, determine the nodal displacements, velocities, and accelerations for five time steps using two finite elements. For simplicity of calculations, let E = 1 × 10⁶ psi, ρ = 1 lb-s² /in⁴, A = 1 in² , and L = 100 in. Use Newmark’s method and Wilson’s method.
