Figure Q1 shows an overhanging beam with pin support at point A and roller support at point B. The beam is subjected to uniformly distributed load from point A to point B and concentrated load at point C, D and E. (a) Calculate the reactions of the beam (b) (b) (4 marks) Construct the shear force and bending moment diagram of the beam and indicate all the important values on each diagram. (12 marks) By considering span DB, determine the distance, d, from point D such that bending moment, M, equals to zero. 80 kN 125 kN 125 kN 5 kN/m D B (4 marks) (20 marks) E E F 3m 3m 2.5 m 3 m 2 m FIGURE Q1
