I need the answer as soon as possible

Extracted text: In the next shed - which is a tri-hinged gantry - the AB pillar also serves as earth containment, with the acting ground load being uniformly variable from 0 to 7 kN/m. On BC and CD roofs, wind loads perpendicular to their axes act, with a value of 5 kN/m. a) Calculate the reactions at supports A and E. b) Make Normal, Shear and Bending diagrams only in the ABC sections, indicating the signs and relevant points of each effort. 5 00 kNm 5.00 kN/m 4.00 m 4.00 m 7.00 kN/m
