For the bar shown in Figure P16–8, determine the nodal displacements, velocities, and accelerations.


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