 4. A final design recommendation justified using the results of your analyses
 
 ### Learning Outcomes
-
+- Apply principles of force balance to model the relationship between thrust, weight, and payload capacity in a quadcopter system.
+- Evaluate design–material combinations using thrust-to-weight ratio, displacement, stress, and factor of safety to determine whether designs meet flight and structural requirements.
+- Develop a 3D CAD model of a drone arm and use MATLAB to perform computational analysis and finite element modeling of its structural behavior.
 
 ## Suggested Background Material

+
+### 6. Finite Element Analysis in MATLAB
+- What FEA is and why it's used
+- Loads and boundary conditions (forces, constraints)

+
+### 7. Engineering Design
+- Iterative design process
+- Tradeoffs between weight and strength, performance and cost (for optional extension)
+- Using quantitative results to justify decisions
 
 ### Optional Extension
 Extend your analysis by formulating and solving an optimization problem to minimize the total material cost of your drone arm. Using your parameter sweep results, identify designs that satisfy all performance constraints (payload requirement, thrust-to-weight ratio, and factor of safety), and determine which valid design achieves the lowest cost. Include the results of your cost optimization analysis in your final recommended design solution for the drone arm.
