Determine the modulus of resilience for each of the following alloys:
$
\begin{matrix} & \text{Yield} & \text{Strength}\\\text{Material} & \text{MPa} & \text{psi}\\\text{Steel Alloy} & \text{830} & \text{120,000}\\\text{Brass Alloy} & \text{380} & \text{55,000}\\\text{Aluminum Alloy} & \text{275} & \text{40,000}\\\text{Titanium Alloy} & \text{690} & \text{100,000}\\\end{matrix}
$
