Question

Problem 2: 2-Node Bar Stiffness Matrix The stiffness matrix of the 2-node bar element discussed in class in 2D...

Accepted Answer

... is constant.

Accepted Answer

... is of size 4x4.

Accepted Answer

... depends only on Young's modulus, the cross-sectional area, the element's undeformed length, and the bar's orientation angle.

Answer

... can be computed by applying a displacement of 1 to all nodes simultaneously and then identifying the resulting forces at all nodes.

Answer

... depends on the nodal displacements.

Answer

... depends only on Young's modulus, the cross-sectional area, and the element's undeformed length.

Answer

... is of size 6x6.
