The beam with L = 6 m below is used to carry two moving loads (9kN and 5kN), a uniform live load of 5 kN/m and a uniform dead load of 2kN/m. Use the Qualitative method to draw the required influence line the determine: (point A is pin, point B is roller, point C is free) 9 kN 5kN D L a) The maximum positive reaction at point B. b) The maximum positive Shear at point D. c) The maximum positive Moment at point D.
