Truss structures are more common than you think. But why do we use them? Beams seem to work fine right, well yes but there is a catch! The trusses are mostly used in bridges, roofs of venues, some cars and many other places. But how do they work and what is their advantage over beams? In this video, we dive deeper on truss structures and the secret to their efficiency. The video is supplemented by a scaled experiment that practically shows the advantages of the truss.
