Consider the beam shown below. Using the 2D beam elements discussed in the notes, if two elements are used to model the system, what is the size of the global stiffness matrix after boundary conditions are applied? In other words, what is the size of [K] that could be used in the calculation to determine the unknown deflection(s) and rotation(s) using: (d)-[K] {f}. We are considering beam elements. Note that the beam has a pinned support at the left end (Node 1) and a clamped support at the right end (Node3). Node 1 1x1 (1 row, 1 Column) O 22 (2 rows, 2 Columns) O 33 (3 rows, 3 Columns) 66 (6 rows, 6 Columns) Node 2 Node 3
