What do you check for before you make a relief cut in the front truss?
(a)
utilizes members that depend on size for strength. The greater the span for a member, the larger it must be to support given load
Conventional Construction
Lightweight Construction
lightweight truss construction does NOT derive strength from size, its obtained from multiple members in compression and tension.
Conventional Construction
Lightweight Construction
