This paper proposes a simple engineering structural analysis problem which can be used to introduce lower division engineering or engineering technology students to the fundamentals of the finite element analysis (FEA) method. Step by step the student sets up the matrix equation which represents the system of simultaneous linear equations which is necessary to solve for the unknown displacements at each of the nodes. They then solve this system of equations using a numerical method which is efficient for large numbers of equations. All of this they do with an inexpensive scientific calculator. As the final step they calculate the stress in each structural member.
