4. Work Principle

The working principle of the simple hydraulic bridge this
is to use a hydraulic piston in accordance with the application
of the principle of Pascal: "The change in fluid pressure
dterapkan closed can not be compressed, distributed and not
reduced to any portion of the fluid and the wall
cross-section. "

5.  If we exert a force on the piston (represented by
injection) containing fluid uncompressed
which is connected with the other piston prop under the
bridge, with the assumption of cross-sectional area both
pistons together, the force applied will be channeled to a
piston that is under the bridge with the same great style.

6.  This causes the piston under the bridge has a style for
lift the bridge so that the bridge can be upwards.
Conversely, if we pull the piston back
as before, the piston under the bridge will be interested
and cause the bridge down.

7. How to making
Hydraulic Bridge???

8. First, prepare all necessary
tools :

9. Ice cream
sticks
Wood glue Cellophane
tape
hose Injection hinge Scisssors

10. break ice cream sticks
that will be used as a
buffer
stacking ice cream
sticks as bridge
support,
and glued with a glue
candles

11. dry the bridge
piers that have
been glued
stacking ice cream
sticks like the picture
on the side, then glued
together using wood
glue, and dry it

12. raft bridge with sticks
of ice that has been
assembled with the
hinge
pole with a rope bridge
and add a hinge, so that
the bridge can be lifted.
strung up like a picture
on the side

13. Connect the house
to the injection,
as shown in the
side
connect the hose to
the hose connector

14. paste injection into
the bottom of the
bridge
hydraulic bridge
is ready to be
used as a
medium of
learning
