Question $1)$ For the frame structure shown,

Determine the reaction and internal forces at $A,B$ and $C.($Hand Calculation$)$

Draw shear and moment diagrams. $($Hand Calculation$)$

Verify your results with a structural analysis software.

The supports at A and $C$ are pin, and the connection at $B$ is hinge. The connections at $D$ and $E$ are fix connections.

$($Take $a=1,b=2,c=5d=4e=1f=1)$ for example abft$=12ft$
