How to build a car? a prototype? a chassis? some quick ideas on structural theory for designing a space frame chassis (or welded tubes or lattice) for #cars! How do triangulated structures and their respective force balances work? Three-hinged arch vs quadrilateral. how much does the diameter of the tubes matter and how much does their thickness matter? how to optimize the weight / torsional stiffness ratio? This topic is often covered in Machine Construction and #Building Science in the mechanical engineering course. The frames used as examples are fromula student (or formula sae), radical and mygale.
