Trusses
Kingpost Truss
Figure 13 shows a simple king-
post truss made from #5 and #4
beams. Use a hanging mass to
apply a load.
Lay the kingpost truss on the
table to compare its horizontal
and vertical stiffness.
To build a three-dimensional
structure, connect two trusses with #4
beams (Figure 14).
Add cross bracing to increase stiffness.
Queenpost Truss
To make a queenpost truss, separate the
kingpost truss in the middle and add a
square section..
Legs can be added to any truss or bridge (Figure 15).
Roof Truss
Use #4 and #5 beams to build a simple roof truss or a roof truss structure with legs.
