For the below illustrated system,

a$.$ Use Moment Distribution $($Cross$)$ Method to plot the bending moment $($M$)$ and shear force

$($V$)$ diagrams.

b$.$ Calculate ${}_i$ values in terms of EI using the Moment Distribution $($Cross$)$ Method.

c$.$ Use Slope$-$Deflection Method to write down the moment equilibrium conditions and

determine ${}_i$ values in terms of $EI.$
