Statically determinate or indeterminate frame analysis by the stiffness method

A$)$ Determine all the displacement components at node $2,$ all the external reactions and

the internal reactions at node $2.$ Show all calculations.

B$)$ Draw the BMD of the frame on the compression side showing all the salient values.

Show all calculations.
