Description
The form of the truss is found graphically by specifying a constant force in the bottom chord. The design is based on the dominant load case, a uniformly distributed load. Use the slider F (bottom chord) to change the magnitude of the constant force in the bottom chord. Use the slider factorQ to add a point load and change its magnitude and see what happens. Use the slider positionQ to move the point load along the span of the truss.
