I need this ASAP. Consider the statically indeterminate beam shown below with the given loading. and are constant. a$)$ Find the rotation at node $2$ using the stiffness method. b$)$ Find the unknown reactions using equilibrium and the force$-$displacement relationships. c$)$ Draw final free body diagrams of the two beam elements and node $2,$ showing all forces with the correct values and directions.

Problem $7$ ; Consider the statically indeterminate beam shown below with the given loading. $E$ and I are constant.

a$)$ Find the rotation at node $2$ using the stiffiness method.

b$)$ Find the unknown reactions using equilibrium and the force$-$displacement relationships.

c$)$ Draw final free body diagrams of the two beam elements and node $2,$ showing all forces with the correct values and directions.
