Each of the following problems involve two$-$dimensional trusses to be modeled using the bar

element $($in some analysis software this may be called a bar, link, spar, or truss element$).$

In each problem, determine:

the magnitude and location of the maximum deflection,

the stress in each member,

and the reaction forces.

Use the computed reaction forces to check the equilibrium.

Note: Node numbers, where included, are for reference only and can be changed at

the analyst's discretion.

Problem $1$:

E$3\mathrm{.}1$ Each member is steel having $E=30({10}^6)$ psi and the cross$-$sectional area is i want a displacement and stress equations from the global matrix that you can find it from the code and make a calculation$)$
