For the beam shown in Figure 1, construct quantitative influence lines for the following functions: (i) Vertical reaction at support A; (7 marks) (ii) Vertical reaction at support B; (7 marks) (iii) Shear force at point D; (7 marks) (iv) Bending moment at point D; (7 marks) (v) (7 marks) (vi) Determine the maximum downward reaction at support A due to a concentrated live load of 120 kN. Determine the maximum upward reaction at support B due to a uniformly distributed live load of 40 kN/m. (7 marks) (vii) Determine the maximum positive bending moment at point D due to a concentrated live load of 110 kN, a uniformly distributed live load of 20 kN/m and a uniformly distributed dead load of 10 kN/m.
