Trusses and bridges

A truss is a lightweight and durable structure, all elements of which work in compression or tension, and do not work in bending. In the video we make several bridges from a sheet of A4 paper and test their strength. Key words: statically determinate system, tensile work, compressive work, structural mechanics, strength of materials. Thank you for your interest in our work!
