Problem $2$: $($FEA of an Euler$-$Bernoulli Beam$)$

Consider the continuous beam $($material property E$,$ geometric characteristics I and L$)$ loaded as shown

in Figure $2.$ Determine:

All nodal displacements and rotations of the given $($original$/$full$)$ beam.

All support reactions of the given $($original$/$full$)$ beam.
