Question

Problem 1: 2-Node Bar Element Which of the following statements is correct for the  2-node bar element  discussed in class?

Accepted Answer

The 2-node bar element is appropriate only for small displacements, because it considers the orientation of the bar to be constant.

Accepted Answer

Each node has    degrees of freedom in    dimensions.

Answer

The 2-node bar element is appropriate for small and large displacements, because it considers the reorientation of the bar through its displacements.

Answer

The stiffness matrix of a 2-node bar element that is oriented vertically (i.e., which points in the   -direction) has 6 non-zero entries.
