Entre dois pilares, encontra-se suspenso um cabo muito resistente. Determine the equilibrium shape of the cable (the catenary), consider the gravitational acceleration, and neglect the stiffness of the cable. Verify the position of the cable at the given test points.
O objetivo deste exemplo é demonstrar um processo irreversível causado pelo atrito. After the loading and unloading, the end-point is in a different position than where it was at the beginning. Determine the movement of the node in the X direction.
