$2.$ You are going to solve the indeterminate beam structure shown below using the Force Method and the set of primary structures shown. Note that the $4$ k $-$ ft moment is applied at Point B$,$ which is in the middle of the beam. EI is constant for this beam.

Compat$$b$$ity Kelationship: $y_C=u$

Determine the deflection at point $C$ as a result of the $4$ k $-$ft applied moment at point $B.$

Important Note: you do not have to solve this entire problem, just provide the term that is asked for above.
