hello there. I'm facing a problem here I need help with please. I have a 1000mm simply supported beam that is under two point loads at 333mm and at 667mm. each point load is 49.8 KN downwards _ _ _|_ _ _ _|_ _ _ I've tried many ways to do that. but I need to know how to use (triangles) to reduce torsion and deflection and surely total mass. here are the phases I worked with and what I reached at the final image. but how do I use triangles ?
