Consider the grid shown in fig 93 given e 210 gpa g 84

Question

Consider the grid shown in Fig. 9.3. Given E = 210 GPa, G = 84 GPa, I = 20 × 10^-5 m⁴, and J = 5 × 10^-5 m⁴, determine:

1. the global stiffness matrix for the structure.

2. the displacement and rotations at node 1.

3. the reactions at nodes 2, and 3.

4. the forces and moments in each element.
