The question. A beam with a solid square cross section of 200mm x 200mm with a length of 30m is simply supported at both ends. Weight of beam = 10kn/m. The beam has a UDL of 120KN which lies between 8m and 20m from the left hand side. I am fairly new to this so please bear with me. I have found moments for r1 and r2 as follows. r1=214kn r2=206kn I need to find the bending moment and shear force however can't remember the method for this. Could anyone just run me through the rough calculations without giving me the answer. Many Thanks.
