Exercise $1$: $2$ beams analysis

$2$ beams connected by a pinned junction are defined in figure below. The characteristics of the problem are:

Fixed support at point A

Pinned Junction at point B$.$

Simple Support at point C $($only vertical displacement null$)$

External forces and Lengths between points defined into the below figure:

Define:

Reactions at points A$,$ B and C

Shear force at each member.

Bending Moment at each member
