A truss is shown in the figure. Support $E$ is pinned and Support $A$ is a roller. All theThe beam is depicted in the figure. Assume $E$ l is constant along the beam. Support A is a roller, B

is a roller and support $C$ is pinned.

$($a$)$ Determine the number of degree of determinacy of the beam.

$($b$)$ Determine the reactions at A$,$ B and C using the force method $($see Week $8).$

$($c$)$ Draw a shear force diagram and bending moment diagram for the beam using the graphical

method. $($Do not need to show the expression for the internal bending moment and internal shear

force$).$

$($d$)$ Compare the hand calculations with the SpaceGass software. Assume the cross$-$section area,

moment of inertia and elastic modulus of each member for SpaceGass software. Comments on

the comparison between the hand calculation solutions and SpaceGass software predictions.

Include SpaceGass analysis results.

members have the same area A and Young's modulus $E.A=4000m{m}^2$ and $E=20$ GPa.

$($a$)$ Calculate the axial force of each member in the real system.

$($b$)$ Calculate axial force of each member in the virtual system.

$($c$)$ By using the method of virtual work $($see Week $7),$ determine the vertical

displacement of joint $D($in mm$,$ round off to one decimal place$).$

$($d$)$ Compare the hand calculations with the SpaceGass software. Comments on the

comparison between the hand calculation solutions and SpaceGass software predictions.

Include SpaceGass analysis results. Please give me the hand calculation answers. I don't need the explanation please
