For the bar subjected to the uniform line load in the axial
direction shown in Figure P3–55, determine the nodal displacements and axial
stress distribution using (a) two equal-length elements and (b) four
equal-length elements. Compare the finite element results with an exact
solution. Let A = 2 in
2
and E = 30 10
