    Torsion Force

     The force works perpendicular to the centre line of the truss but is not positioned in the same plane as the centre line. This force tries to twist the truss. Here are some situations where...

    Truss definition

     When the first lattice spans appeared in events in 1970s, people just describe a truss as follows: A modular structural element made of aluminum tubes welded to each other used to support stage...
