Please solve these question in details and explaination. Thank you so much in advance.

Draw the shear force and bending moment diagrams for the beam given below. Determine the maximum bending moment in segment AB and its location from point A. Neglect the weight of the beam. 40 mm: 20 RN c) Express the shear force and bending moment as functions of x (the reference coordinate system is placed at point A) for segment AB and determine the shear force and bending moment at the points located just right of point A and just left of point B. d) Express the shear force and bending moment as functions of x (the reference coordinate system is placed at point A) for segment BC and determine the shear force and bending moment at the points located just right of point B and just left of point C
