According to the Colombian bridge code $($CCP$-14),$ the live load can be modeled with a tandem $($trailer$)$ design and a load line. The tandem loading is modeled with point forces on each axis and the load line is a uniform distributed force as presented in Figure $1$a$.$ Perform the following activities for the typical beam presented in Figure $1$b:a$)$ Report the reactions of the supports.b$)$ Calculate and draw the shear diagram of the typical bridge girder.c$)$ Calculate and draw the moment diagram of the typical bridge girder.d$)$ Draw the shear and moment diagram
