Analysis
The design of the Cubesat 5000 is driven by the weight and impact requirements. The initial analysis were based on the weight of different materials to determine which method would be the most efficient. Subsequent analysis (see appendix A.8) were focused on the actual weather balloon launch and flight analysis (drag force for the area of the cube, parachute drag calculations, length of free fall calculations), and then the later calculations were done on the impact and stresses of the material.

Several of the analysis were done to determine which material would be used for optimum strength and structural integrity. One of the options considered was poplar wood, since it was lightweight and a relatively soft wood which would make it easy to machine. The final design consists of 3D printed parts instead due to the time it would save and the cost required to manufacture the wood. Since the final design is also needs to be something that the CWU Physics department can manufacture again.

The total design was then optimized from the initial design since the weight was more than allowed. The lid mechanism was then analyzed to determine if the lid would be able to survive the final impact after launching.
