Key Findings
- 01No structural failure was predicted for either galvanized steel or aluminum alloy blades under the simulated critical loading conditions.
- 02The factors of safety for all components, even for the less robust material (aluminum), were greater than 1.
- 03Maximum displacements of 3.84 mm (galvanized steel) and 6.81 mm (aluminum) were observed at the blade tips, which were deemed acceptable relative to the structure's size.

Limitations
FEA models are only as good as the input data; inaccurate material properties or load assumptions will lead to inaccurate results. Real-world conditions often involve dynamic forces and environmental factors not captured in static analysis.
Reliability & validity
The reliability of FEA depends on the accuracy of the mesh, material properties, and applied loads. Validity is enhanced by comparing simulation results with theoretical calculations or experimental data, which was not performed in this study.
Think critically
How might the results of this static analysis differ if dynamic forces, such as wind gusts or vibrations, were considered?
