The document describes an automatic hydraulic jack project. It provides background on hydraulics, including Pascal's law and the relationship between pressure, force and area. It then discusses the basic components of a hydraulic system, including a pump, motor, valves, conduits and controller. The project uses syringes to act as actuators and directional control valves. Water is used as the transmission medium, with the syringes working together to lift a load automatically via gears, a motor and controller. Advantages include easy operation and control while disadvantages include potential rupturing losing needed pressure.

3. Hydraulics is a topic in applied science
and engineering dealing with the
mechanical properties of fluids or
incompressible fluid.
On a very basic level Hydraulics is used
for the generation, control and
transmission of fluids in order to
produce some mechanical work or in
general as a part of engineering.

4.  Pascal's Law: It states that pressure exerted anywhere
in a confined incompressible fluid is transmitted equally in
all directions throughout the fluid
such that the pressure ratio
(initial difference) remains the
same. The Hydraulic jack,
Hydraulic press and Breaking
system for automobiles are some
examples of application of this law. .

5.  The relationship between pressure, force and area is
given by
P=F/A
 This relationship is very useful for obtaining a
mechanical advantage.

7. •Fluid power deals with the control and transmission
of energy through the use of pressurized fluids.
•Fluid power is quite literally the force behind
industry because it is used to push, pull, drive and
regulate virtually all machines used in industry.
•Fluid power is used in the steering, brake system,
and automatic transmissions of cars and trucks
• Since fluids exist as either a liquid or a gas, fluid
power is a term used to describe both hydraulics and
pneumatics.

2. Electric Motor (prime mover)
3. Valves
4. Conductors (pipes, tubes and hoses)
5. controller

10.  Tools: steel rule, saw, jack plain,
chiesel, file, .
 Materials: wood, plastic syringe,
rubber tubes, small plastic bottle,
Steel balls, spring, gears shaft,
electric motor, controller, wire .

11.  Our project is based on the same laws that are
mentioned before.
 Syringes are used as actuators as well as the
switches.
 The medium of transmission is water.
 The whole project uses three syringes and in each
syringe is acting as the actuator and the other one
acts as the direction control valve .
 We can also use syringes of different
diameter.

12. In automatic hydraulic jack, the P1 (piston) of C1 (cylinder) move the upper
direction then the V1 (valve) is open and the liquid is sucked in C1 by the pipe.
And the P1 moved in downward direction then V1 is closed and the V2 is open
or the liquid is entered in C2 and the P2 moved upward direction with the help
of gear shaft & motor then the liquid flow in C3 and the V2 is closed or the
liquid entered in C3 then P3 move upward direction. The C2 & C3 are both
attached to each other or when the pressure are applied on P2 then the P3 jack
the work piece or material automatic with the help of motor & controller.

14. Advantages:
• The hydraulic system easy to operate & control.
• The hydraulic system has light weight.
• The hydraulic system can realize automatic overload
protection.
• The hydraulic system can be easy & flexible to arrange a as
needed.
Disadvantages:
• The hydraulic system easily ruptured.
• It will lose its needed pressure and will fail.
