Problem #$1$:

a$.$ Referring to the structural system shown in Text Problem $2\mathrm{.}23,$ determine the force in each member of the truss. Summarize member forces in a table $-$ identical to the one shown below.

$\backslash$table$[[,,\backslash$table$[[$Force sense$],[($T: tension; C:$],[$compression$)]]],[$AB$,$Force $($axial$),$ kN$,],[$BE$,,],[$ED$,,],[$DC$,,],[$DB$,,],[$DA$,,]]$

b$.$ Determine the average normal stress in member AB$.$ Please include a dimensioned sketch of member AB x$-$section $($section perpendicular$/$normal to member axis$).$ Recall stress is the "intensity of a force"... how much force you have per unit area.

c$.$ Knowing that all materials are deformable, based on intuition, would you expect point $E$ to move to the left or right of the position shown on the figure.
