Question: A structure is composed of two one-dimensional bar elements. When a (10 mathrm{~N}) force is applied to node 2, calculate the displacement vector ({mathbf{Q}}^{mathrm{T}}=left{u_{1}, u_{2},

A structure is composed of two one-dimensional bar elements. When a \(10 \mathrm{~N}\) force is applied to node 2, calculate the displacement vector \(\{\mathbf{Q}\}^{\mathrm{T}}=\left\{u_{1}, u_{2}, u_{3}ight\}\) using the finite element method.

u2 10 N 1 Element 1 2 Element 2 3 k =

u2 10 N 1 Element 1 2 Element 2 3 k = = 200 N/m k = 300 N/m
