Revised Design and Sims
The front landing gear had cutouts applied so that the weight of the part can be reduced.
Objective of Sim
[The goal of the sim is to ensure that the cutout holes do not reduce the integrity of the part enough so that it would fail on landing.]
Simulation Setup
Assumptions and Preliminary Calculations
Assuming that Eclipse is 5kg
Fg = 5(9.81)
= 49.05
Applying a safety factor of 3, 150 newtons was applied to the part
Used Aluminum Alloy
Applied Loads
Load was applied to both axle holes
...
Fixtures
The mounting holes are the fixture for the test.

Could also include minimum safety factor.
Conclusion
The landing gear will be able to survive landing
