The structure shown in the below figure is fixed at Node A and constrained with roller support at

Node C$.$ The structure is subjected to both concentrated vertical load P $=30$ kN and bending moment

M $=30$ kN$.$m at Node B$.$ Assume EI is constant.

i$.$ Determine the degree of static indeterminacy $($DSI$),$ i$.$e$.,$ the excess of unknown actions than

the available number of equations of static equilibrium.

ii$.$ Find the reaction at support C using the flexibility $($force$)$ method of analysis.

iii. Draw the shear force diagram $($SFD$)$ and bending moment diagram $($BMD$)$ showing all the

peak values.
