2. Arch Bridges.
The purpose of an
arch bridge is to hold
heavier loads without
collapsing.
The materials that
consist of this bridge
are what looks to be
mud and stone.

3. Arch Bridge.
The definition of an
arch Bridge is a
bridge supported by
an arch or a series of
arches.
In this arch bridge
you can see the
keystones. A
keystone is the
central building
block at the top of an
arch or vault.

4. Suspension
Bridge
The definition of a
suspension bridge is
a bridge having it’s
roadway hung from
large cables
supported between
tall towers

5. Suspension
bridge
The purpose of the
suspension bridge is
that the bridge has
cables between
towers plus vertical
suspender cables
that carry the weight
of the deck below.

6. Truss Bridge
The definition of a
truss bridge is a
bridge supported by
trusses
The definition of a
truss is a framework
of beams that form
triangles; for
example, your force
pulling an elastic.

7. Truss Bridge
The purpose of a
truss bridge is to
carry heavier loads
like big loading
trucks or oil trucks.
The trusses make it
so that the bridge
doesn’t collapse
under heavier loads.

8. Beam Bridge
The definition of a
beam bridge is a
bridge supported by
a beam or several
beams.

9. Beam Bridge
The beam bridge is
the most commonly
used bridge
The purpose of the
beam bridge is a
simple beam bridge
is flat and is
supported by two
ends.

10. Solid Structure
The purpose of a
solid structure is a
structure that has
little or no space
inside, and relies on
its own mass to resist
the forces that act on
it.

11. Solid Structure
The definition of a
solid structure is-
A solid structure is
formed from a solid
piece (or solid
combination of
pieces) of some
strong material.

12. Frame Structure
The strength of a
frame structure
comes from the way
the components are
joined. Individually,
no one component of
a frame structure is
as strong as the
components
combined.

13. Frame structure
A frame structure is
made up of a rigid
arrangement of
parts, or structural
components,
fastened together. An
example is your
skeleton, which is
made up of bones,
ligaments, and
joints.

14. Shell Structures
The definition of a
shell structure is a
structure with a solid
outer surface (which
may be rounded or
flat in shape) and a
hollow inner area.

15. Shell Structures
Shell structures with
a rounded outer
surface are usually
stronger than those
with a flat outer
surface, because the
curved areas
distribute the load
around the whole
surface.
