roof truss



























one roof making company calls the various truss designs:
Howe truss
Fink truss
Attic truss

which one uses most wood?

quite long and complex calculations involving the sine and cosine rule

symmetry is assumed

the Fink truss does not have struts that are perpendicular to the main, 6m lengths (even though it looks like they might be)
