A statically indeterminate beam is loaded with uniformly distributed load from $A$ to $B$ and concentrated load at joints D as illustrated in Figure Q$2.$ The total length of the beam is $10m$ support at $A$ is pinned, and $B$&$D$ are rollers.

i$)$ Identify the indeterminacy of the beam element.

ii$)$ Using the Moment Distribution Method determine the support reactions at A$,$ B$,$ and C of the beam.

iii$)$ Sketch the shear force and bending moment diagram.help
