What is a truss bridge?
A bridge supported by arches.
A bridge made entirely of concrete.
A bridge whose load-bearing superstructure is composed of a truss.
A bridge that floats on water.
Which of the following is NOT a type of truss bridge?
Warren
Pratt
Howe
Cantilever
What distinguishes a Warren truss bridge from others?
Its use of vertical members.
Its exclusive use of concrete.
The triangular webbing that spreads out the load.
Its ability to float on water.
In a Pratt truss bridge, where are the diagonal members located?
Sloping down towards the center of the bridge.
Sloping up towards the center of the bridge.
Parallel to the horizontal components.
There are no diagonal members in a Pratt truss bridge.
How does a Howe truss bridge differ from a Pratt truss bridge in terms of member orientation?
Howe has diagonal members sloping up towards the center, while Pratt has them sloping down.
Howe uses only horizontal members, while Pratt uses vertical.
Howe is made entirely of concrete, while Pratt uses steel.
There is no difference in member orientation between Howe and Pratt truss bridges.
What is the primary function of the truss in a truss bridge?
To decorate the bridge.
To support the deck and distribute loads.
To make the bridge longer.

What role do the vertical members play in a Pratt truss bridge?
They resist tension.
They resist compression.
They are purely decorative.
They support the diagonal members only.
In terms of load distribution, what advantage does a truss bridge offer?
It concentrates the load at a single point.
It evenly distributes the load across the entire bridge.
It moves the load to the bridge's ends.
It eliminates the need for a foundation.
Why might an engineer choose a Howe truss design over a Pratt truss design?
For aesthetic reasons only.
If the bridge needs to support heavier loads and resist greater tension.
If the bridge is over water.
If the bridge needs to be longer than usual.
