Measurements of the A$227$ Hard$-$drawn wire spring is given in the figure, without any load applied, before set

removed.

$($a$)$ What is the end type, number of end coils, number of total coils, and number of active coils, solid

length and pitch of the given spring?

$($b$)$ Determine the torsional yield strength of the wire.

$($c$)$ Determine the static load corresponding to that yield strength.

$($d$)$ Determine the deflection corresponding to that static load.

$($e$)$ Will there be a set removal if this spring is compressed to solid and then released?

$($f$)$ Is buckling possible for the given length? Is an inside rod or exterior hole may be needed?

$($g$)$ For fractional overrun to closure $($robust linearity$)=0\mathrm{.}15$ and factor of safety at closure $($solid height$)$

$n_5=1\mathrm{.}2,$ what will be the maximum force that should be applied on this spring?
