\subsubsection{Sensor Array Material Calculations}
The initial estimate of the weight of the sensor array was $800~\mathrm{g}$.
The selected material for the lines under tension lifting the sensor array was 10-pound test fishing line,
which has a yield strength of $45~\mathrm{N}$.
With four lifting points at the corners of the sensor array,
it is unlikely that any line holds more than 50\% of the weight,
but assuming for the purposes of the the calculation that a single point holds 100\%,
the maximum load is $0.8~\mathrm{kg} \times 9.82~\mathrm{m \cdot s^{-2}} = 7.9~\mathrm{N}$.
This gives a factor of safety of $5.65$ under an extremely unlikely scenario,
so the material selection is valid.
