Nuts installed on a piece of all$-$thread experience the following forces in service:

The length of each segment is given by$.$

If the all$-$thread is composed of a material that has an elastic modulus of $30000$ ksi $,$ and its effective diameter is $0\mathrm{.}4$

inches, determine the following:

$($a$)$ The maximum normal stress in this piece of all$-$thread.

$($b$)$ The change in length of segment $AB.$

$($c$)$ The change in length of segment $BC.$

$($d$)$ The change in length of segment $CD.$

$($e$)$ The change in length of the whole length of all$-$thread.

Under the following assumptions:

Bearing stress between threads of the all$-$thread and the nut may be neglected

Stress concentration effects may be neglected

The forces that the nuts apply may be treated as concentrated forces at each location.

The nuts may be treated as rigid.

The force applied to each nut is distributed evenly around the nut's perimeter.

$($a$){}_{\text{m}\text{a}\text{x}}=$

$($b$){}_{AB}=$

$($c$){}_{BC}=$

$($d$){}_{CD}=$

$($e$){}_{\text{t}\text{o}\text{t}\text{a}\text{l}}=$
