that is my design. it is a cantilevered 1/2 of a bridge which with be loaded at the end. the ultimate goal is to build the lightest wooden bridge that bears most loadI need to change the beam under the bridge in 3 different variations and then draw the diagrams and calculate moments, boundary conditions, max bending shear and axial stresses for each.so one variation is changing height of beam
second is changing width of beam and third is making it two or three beams
