TRUSS BRIDGE
EXPERIMENT 9
HERE’S HOW
Repeat Experiment 7. Compare the
amount of deflection in the different
bridges. Which bridge is the strongest?
Engineering constraints
BONUS EXPERIMENT
Can you build this
alternate truss bridge?
WHAT’S HAPPENING
Adding the trusses to the bridge results
in a bridge that deflects much less under
the same load. The trusses distribute
the forces through the bridge in such a
way that the middle of the bridge
deflects less. Some of the rods in the
truss are under compression and some
are under tension, and each rod and
connection point is suitably strong to
hold up to the forces acting on it.
Read about tension and compression
on the next page.
A crucial task of an engineer is to
identify and understand
constraints in order to develop a
solution. An engineer has to
balance many different trade-
offs. Some trade-offs an engineer
may face include available
resources, cost, productivity,
time, quality, and safety.
