The truss shown has constant EA for all members. $E=29,000$ksi and $A=1i{n}^2.$ Using the

force$/$flexibility method,

a$.$ Determine all support reactions. $[10$ points$]$

b$.$ Determine the force in each member. Be sure to state if the member is in tension or

compression. $[8$ points$]$

c$.$ Determine all joint displacements. $[8$ points$]$

d$.$ Use MASTAN $2$ to model the truss and verify your answers. Ensure that the node

numbers in your model match the node numbers shown in circles and the element

numbers match those shown in squares. Attach a screenshot of your model, the

axial force diagram and the support reactions calculated by MASTAN$2[4$ points$]$
