$(18$ points$)$ Difficulty $(4/5)$

Given the truss shown, loaded and dimensioned with the values given here:

$\left[\begin{array}{ccc}a& F_1& F_3\\ b=6\mathrm{.}6ft& F_2=2100vb& F_4=1100vb\\ c=8\mathrm{.}1ft& ?& ?\end{array}\right]=8\mathrm{.}1ft=1100vb=2100vb=6\mathrm{.}6ft=2060Nb=8\mathrm{.}1ft=1100vb=2100vb=6\mathrm{.}6ft=2060Nb=1000Jb=8\mathrm{.}1ft=1100vb=2100vb=6\mathrm{.}6ft=2060Nb=1000Jb=4\mathrm{.}1ft$

Find the following, assuming the truss does not deform out$-$of$-$plane:

$($a$)$ The reaction forces at the supports.

$($b$)$ The forces carried in each member.

$($a$)$

Reactions:

$($If the support applies an upward or rightward force on the stucture, enter a positive value, otherwise enter a negative value$)$

$($b$).($c$),$ and $($d$)$

Members:

$($Denote tensile forces with positive velues and compressive forces with negative values. Enter NA for the diameters and changes in length of compressive and zero$-$force members.$)$
