Question

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 following locations: (a) x=6m (b)x = 12 m (c) x= 15 m When entering your answers, use the bending moment sign convention. Please Answer: (a)M= kN-m. (b)M = kN-m. (c)M= kN-m.
