A beam 15 m long is simply supported at the left end and at 3 m from the right end. It carries concentrated loads of 40 and 20 kN at 6 and 9 m respectively from the left support, and another concentrated load of 50 kN at the extreme right end. Sketch and dimension the shearing force and bending moment diagrams.

can you help me on part 3 and 4

(a) A simply supported beam of length 6 m carries point loads of 5 kN each at a distance of 1.5 m and 3.5 m from the left end support. The beam carries a uniformly distributed load of 1 kN/m between the point loads. Draw the shear force and bending moment diagram.

Please answer Part 3, thank you PART 1 Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a= 6 m, b = 3 m, PB = 70 kN, Pc= 100 kN, and PE= 30 kN. Construct the shear-force and bending-moment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise. Calculate the reaction forces Ay and Dy acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown on the free-body diagram below. (Note: Since Ax= 0, it has been omitted from the free-body diagram.) Answer: Ay = 50 kN Dy= 150 kN PART 2 Determine the shear force acting at each of the following locations: (a) x = 3m (b)x= 9 m (c)x = 13.5 m (d)x= 18 m When entering your answers, use the shear force sign convention. Answers: (a) V= 50 kN (b) V= -20 kN (c) V= -120 kN (d)V= 30 kN PART 3 (PLEASE ANSWER, THANK YOU) Determine the bending moment acting at each of the…
