**Given:**

**Find:**

**Find the displacements of the three bodies and the forces ( tensile/compressive) in the springs. What are the reactions at the walls? Assume only horizontal translation.**

**Solution:**

**The nodes and elements are labeled in the problem. Create a connectivity table.**

**Construct Elemental equilibrium equations for all 6 elements. **

**Here is a sample equilibrium equation for element 3:**

**The notation for : The superscript parenthesis signifies the element number, while the subscript signifies the associated node number.**

**With element forces calculated, a node equilibrium can be established.**

**Start with a free-body diagram of each node, and then create the equation:**

**Make sure all forces are positive and modeled in tension.**

**Combine your elemental equilibrium equations with your nodal equilibrium equations for the global stiffness correlation:**

**Solving with MATLAB:**
