Using the force method, calculate the bending moment at $D$ for this one$-$fold statically indeterminate frame. Ignore the axial and shear deformations and consider $EI$ constant for the whole frame.

Please use the gradual solution below and release $M_{\text{I}}$ as the redundant moment. Take $a=14kN$ and $L=1\mathrm{.}9m.$

Part $1)$

Draw the bending moment diagram of the primary structure and calculate the bending moment at $A,D$ and $H.$

a$)M_A^1=$

kN m

Your last answer was interpreted as follows: $0$

b$)M_D^1=$

kN m

Your last answer was interpreted as follows: $\frac{-133}{15}$

c$)M_H^1=$

kN m

Your last answer was interpreted as follows: $-14$

Part $2)$

Draw the bending moment diagram of the redundant structure when applying a counter$-$clockwise unit moment at I. Calculate the bending moment at $A,D$ and $H.$

a$)m_A=$

kN m

Your last answer was interpreted as follows: $1$

b$)m_D=$

kN m

c$)m_H=$

kN m

Your last answer was interpreted as follows: $0$

Part $3)$

Calculate the real bending moment at $D$
