PART B
Evaluate the unknown nodal displacements and reactions for the truss of shown above using the stiffness method.

PART C
For the truss shown above, evaluate the member forces of each element using the stiffness method and specify whether there are in compression or tension.

PART D
Compare the hand calculations with the SpaceGass/ABAQUS software and comments on the comparison between them. You need to include software analysis results.

PART E
Compare the hand calculations with the Matlab calculations and comments on the comparison between them. You need to include screenshot of Matlab input and output files in your assignment.
