The device serves as a compact torsional spring. It is made of A$-36$ steel and consists of a solid inner shaft $\backslash ($ C B $\backslash )$ which is surrounded by and attached to a tube $\backslash ($ A B $\backslash )$ using a rigid ring at $\backslash ($ B $\backslash ).$ The ring at $\backslash ($ A $\backslash )$ can also be assumed rigid and is fixed from rotating. A torque of $\backslash ($ T$=2\mathrm{.}2\backslash$mathrm$\{$kip$\}\backslash$cdot $\backslash$mathrm$\{$in$\}\backslash ).$ is applied to the shaft. $($Figure $1)$
