• Formulating basic laws of fluid dynamics
• Applying the basic laws of fluid dynamics in everyday physics problems
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 wallcross-section. "
If we exert a force on the piston (represented by injection) containing fluid uncompressedwhich 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.
This causes the piston under the bridge has a style forlift the bridge so that the bridge can be upwards. Conversely, if we pull the piston backas before, the piston under the bridge will be interested and cause the bridge down.
How to making Hydraulic Bridge???
First, prepare all necessary tools :
Ice cream sticks
Wood glue
Cellophane tape
hose Injection hinge Scisssor
s
break ice cream sticks that will be used as a buffer
stacking ice cream sticks as bridge support, and glued with a glue candles
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
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
Connect the house to the injection, as shown in the side
connect the hose to the hose connector
paste injection into the bottom of the bridge
hydraulic bridge is ready to be used as a medium of learning
