Engine Mount
We had to design an engine mount that can support a 250 lb Lycoming o-300 engine. The firewall must be grounded as the stable part of the frame using 7 fixed constraint points. The structure will support a 250 lb engine which will be attached via the 3 engine mounting points. The structure must be able to withstand -3Gs and positive 6Gs. The structure members will be 1 1/2 in. ANSI pipe. The frame members should be mitered and trimmed.
Procedure:
In preparation for this project we did two tutorials, one about framing, mitering and trimming. The other tutorial taught us how to create a simulation in which we could pin the material and add stress to it. We researched materials to use and found that titanium would be the best one to use but in the end it would be too expensive and costly so we went with mild steel. While following the constraints Thomas edited the frame and added the ANSI Pipes and also mitered and trimmed it to fit the frame.

Solution:
After doing the two differing stress tests, one being -3g and the other 6g they met the constraints as it had a displacement lower than .007. We went with mild steel because of its adequate strength to weight ratio and low cost. The main drawback from using mild steel is it's heavy weight.

Conclusion:
I learned the pros and cons of different materials such as steel and titanium. I researched the materials and tried to help Thomas out with creating the frame. Thomas did the majority of the work on the frame and Andrew did all the calculations to find the weight distribution. Inventors frame tool is useful as it allows engineers to find certain strain on materials and structures without having to actually test it in real life.
