Question

Draw the influence lines for bar forces in mem-
bers HD and HC of the truss shown in Figure P12.33.

The load moves along the bottom chord of the truss. If the
truss is to be designed for a uniform live load of 0.32 kip/ft

that can be placed anywhere on the span in addition to a
concentrated live load of 13 kips that can be positioned

where it will produce the largest force, compute the maxi-
mum tension and compression forces in bar HD.
