Theory
Hydraulics is a topic in applied science and engineering that deals with the mechanical properties of liquids. Pneumatics is a topic that deals with the study and application of the use of pressurized gas to affect mechanical motion.
Blaise Pascal described the behavior of a fluid (gas or liquid) in a closed container. Pressure applied to an enclosed
fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container. A hydraulic lift
is an example of a device that demonstrates the principle. A model of a hydraulic (or pneumatic) lift consists of a
syringe that has a large diameter piston connected to another syringe that has a small diameter piston. The pressure
is the ratio of force to area and will be the same throughout the system. For example, if the large diameter piston
has an area five times larger than the small diameter piston, the hydraulic lift will have a theoretical mechanical
advantage of five to one. In other words, a force of 10 N applied to push the small piston into the syringe would
cause a force of 50 N to be applied to push the large piston out of the piston. The large piston does the same
amount of work as is done to the small piston. The distance that the small piston is pushed into the small syringe is
five times more than the distance that the large piston will move out of the large syringe.
About the Components
Syringes
The set has three sizes of syringes (60 mL, 20 mL, and 10 mL), each with a male luer (pronounced “loo-er”) lock
at one end. The luer lock allows the syringe to be connected to couplers (tubing) or valves. There is a retainer ring
on the inside of the large end of the cylinder that helps prevent the piston from being pulled out of the cylinder too
easily.
Hydraulic Cylinder
The hydraulic cylinder is a modified 60 mL syringe with six trunnions (cylindrical protrusions used as a mounting
or pivot point) on the cylinder and two mounting holes on the end of the syringe. The holes allow the hydraulic
cylinder to be mounted between two axles. When the hydraulic cylinder is attached to a structure and a gas (such
as air) or a liquid (such as water) is pumped into the cylinder, the pressurized fluid will cause the piston to be
pushed out of the cylinder. The part of the structure that the piston is attached to will move.

Cylinder
Figure 6: Check Valve Assembly
Couplers
Pressure Sensor Coupler
The pressure sensor coupler has a “T” shape. The shorter arms
of the “T” have a male luer lock at one end and a female luer
lock at the other. The longer arm of the “T” has an inline quick
connector at the end for connecting to the pressure port on a
pressure sensor. Push the inline quick connector onto the pressure port, and turn the quick connector clockwise (left to right)
until the connector locks in place.
Syringe Coupler
The syringe coupler is a length of tubing about 27 cm long with a female luer lock
at each end. For example, the coupler connects one syringe to another, or a syringe
to the hydraulic cylinder. The syringe coupler can also connect to the other couplers and to the valves. The female luer lock screws into a threaded male luer lock.
Extension Tubing
The extension tubing is about 60 cm long with a female luer lock at one end
and a male luer lock at the other. It can be used to increase the distance
between components of the hydraulics structures set.
Valves
O-Ring Drive Belt
Bleeder Valve
The bleeder valve has a stopcock that can be opened and closed to allow
fluid to flow through the valve or not. When the stopcock handle is perpendicular to the tubing, the valve is closed. When the stopcock handle is parallel to the tubing, the valve is open.
Check Valve Assembly
The check valve assembly is a “T” shaped assembly that
has two one-way valves that allow fluid to flow through
the valve in specific directions. For example, when the
check valve assembly is connected to a syringe, fluid can
flow into the cylinder of the syringe through valve A when
the piston is pulled out. When the piston is pushed in, fluid
can flow out of the cylinder through valve B. The arrow on
each valve indicates the direction that fluid may flow
through the valve.
The included O-ring can be used as a ‘drive belt’ when it is
looped from one pulley to another pulley, or from a pulley
to a Rotary Motion Sensor.
Operation
To demonstrate Pascal’s Principle as described in the Theory section, connect the 60 mL syringe to the syringe
coupler. Pull the piston halfway out. Get a 20 mL syringe and pull its piston halfway out. Connect the smaller
syringe to the syringe coupler. Have one person hold the 60 mL syringe and another person hold the 20 mL
syringe. Have each person push in the piston of their syringe. You should notice that it is much harder to push on

the piston of the smaller syringe than it is to push on the piston of the larger syringe. Can you push the 20 mL
syringe’s piston all the way in? If so, can you push the 60 mL syringe’s piston all the way in while holding the 20
mL syringe’s piston in place?
To find out how the various components work together, set up the following combination of parts: 20 mL syringe,
check valve, bleeder valve, syringe coupler, and hydraulic cylinder. Start with the pistons of both the hydraulic
cylinder and the 20 mL syringe pushed all the way in.
• Connect the check valve assembly to the 20 mL syringe.
• Connect the bleeder valve to the check valve assembly.
• Connect the syringe coupler from the bleeder valve to the male luer lock on the hydraulic cylinder.
• Twist the handle on the stopcock of the bleeder valve to the closed position.
• Pull out the piston of the 20 mL syringe until the tip of the piston is at the 20 mL mark on the syringe.
• Next, push the piston of the syringe all the way in. What happens to the hydraulic cylinder? You should have
noticed that the piston of the hydraulic cylinder moved out until the tip of the piston was close to the 20 mL
mark on the cylinder. Try it again.
• Pull the piston of the 20 mL syringe so the piston is next to the 20 mL mark. Did the piston of the hydraulic
cylinder go back into the cylinder as you pulled the piston out of the syringe? The piston of the hydraulic
cylinder should not have moved because the check valve assembly only allows fluid to flow in specific
directions. Next, push the piston of the syringe all the way in. The piston of the hydraulic cylinder should
move to the 40 mL mark (approximately).
• Repeat the procedure a third time and see whether the piston in the hydraulic cylinder was able to move to
the 60 mL mark.
To empty the hydraulic cylinder without disconnecting any tubing, twist the handle of the stopcock to the open
position and push the piston of the hydraulic cylinder all the way in. Fluid can flow out of the bleeder valve, but
cannot go back into the cylinder of the 20 mL syringe because of the one-way check valve.

Using a Liquid Instead of a Gas
Fill a syringe with a liquid. Connect the syringe to the syringe
coupler. Push the piston slowly to force liquid from the
syringe into the syringe coupler until all the air is pushed out
of the coupler. Finally, connect a second syringe (or the
hydraulic cylinder) with the piston all the way in to the liquid
filled syringe coupler. When you push on the piston of the liquid filled syringe, the liquid will push against the piston of the
second syringe (or cylinder).
CAUTION: If you use the Pressure Sensor Coupler and a
pressure sensor in your hydraulics structure, be sure that no
liquid enters the pressure port of the sensor. Liquid can go partway into the tubing of the Pressure Sensor Coupler
where it connects to the sensor, but leave an air space in the tubing between the liquid and the sensor.
Using a Rotary Motion Sensor to Measure Volume
You can mount a Rotary Motion Sensor (PS-2120) on a rod and attach the rod to your hydraulics structure using
Structures Rod Clamps* (ME-6986). Please see the illustration of the Hydraulic Boom on page 8. Use a thumbscrew to secure a Drive Wheel* to an axle that will turn when a part of the structure moves. Arrange the sensor and
drive wheel so that the included O-ring will fit over the drive wheel and the largest pulley on the sensor.
Use the data acquisition software to calibrate the Rotary Motion Sensor. Set the structure so that the volume in the
hydraulic cylinder is zero. In the software, set the corresponding position of the Rotary Motion Sensor to be 0 mL
(zero milliliters). Move the structure so that the volume in the hydraulic cylinder is at its maximum. Set the corresponding position of the Rotary Motion Sensor to be the maximum volume (e.g., 60 mL).
Adding Load Cells
To measure the compression and tension forces in individual members of a structure, add load cells (e.g.,
PASCO Model PS-2200 or PS-2201) to any PASCO
Structure. Replace a beam with two shorter beams and a
load cell.
#5 beam = load cell + two #3 beams
#4 beam = load cell + two #2 beams
#3 beam = load cell + two #1 beams
*Included in the
Advanced
Structures Set.
Use thumbscrews to attach two beams to a load cell as shown in the figure.
When using load cells, assemble your structure with the screws loose. This
will simplify the analysis by ensuring that the members experience only tension and compression without moments.
Calibration
See the instructions that came with the load cells for details about how to connect the load cells to an interface or datalogger. Follow the instructions to calibrate the load cells and use them to collect data. (Load cells are factory
calibrated; however, you can re-calibrate them in software or on the datalogger. See the documentation for your software or datalogger for instructions.)

Ideal Gas Law
Introduction
The Ideal Gas Law Apparatus, TD-8596A, allows simultaneous
measurements of temperature and pressure of a gas as it is compressed. A low thermal mass thermistor is built into the base of
the syringe to measure temperature changes inside the syringe.
The response time is around 0.5 second. The plunger is equipped
with a mechanical stop that protects the thermistor, and also
allows for a predetermined change in volume. The apparatus has a
mini stereo plug temperature connector that connects directly to a
port on a temperature sensor and a quick-release pressure connector. As the plunger of the syringe is depressed, the volume
decreases while pressure and temperature increase. NOTE: This
experiment requires the “A” version of the Ideal Gas Law Apparatus.
Equipment Setup
Use the Hydraulic Boom structure with the Ideal Gas Law Apparatus (TD-8596A) and the Pressure/Temperature
Sensor (PS-2146).
• Unscrew the male luer lock at the base of the Ideal Gas Law (IGL) Apparatus to remove the short
quick-release connector from the apparatus.
• Connect the Pressure Sensor Coupler to the female luer lock on the base of the IGL Apparatus in place of the
quick-release connector.
• Connect the side arm of the Pressure Sensor Coupler to the pressure port on the Pressure/Temperature
Sensor.
• Connect the Syringe Coupler from the Pressure Sensor Coupler to the Hydraulic Cylinder.
• Plug the mini stereo plug of the Temperature Connector from the IGL Apparatus into the
temperature port on the Pressure/Temperature sensor.
• Plug the Pressure/Temperature Sensor and the Rotary Motion Sensor into a
PASCO Interface. (NOTE: You may want to use a PASport Extension
Cable to connect the Pressure/Temperature Sensor to the interface.)
