PLEASE ANSWER QUESTION (a)

PLEASE ANSWER QUESTION (a) An oblique frame ABCD An oblique frame ABCD as shown in Figure Q2 is fixed to the foundations at A and D, and has two internal hinges at M and N and carries a concentrated load of 20kN between them. a) Calculate the moment reaction at D. Use the flexibility method. El is constant. (CO1,PO2)(C3) b) If the base at D was later found wrongly detailed that it instead acts like a pin, draw the quantitative bending moment diagram for the girder BC between the two hinges. (CO1,PO2)(C5) Figure Q2
