Worksheet time: 10mins
What is the main function of a pneumatic system?
To generate electricity
To move liquids through pipes
To use compressed air for mechanical work
To produce chemical reactions
Which of the following is NOT an advantage of pneumatics?
Clean operation
High energy efficiency
Safe when used correctly
Readily available
Compared to hydraulics, pneumatics generally produces:
Larger forces
Smaller forces
The same amount of force
No force
Which of the following is a key safety precaution when working with pneumatic systems?
Direct compressed air at your skin to test it
Tie back long hair and wear goggles
Keep loose airlines unconnected
Always increase air pressure to the highest level
What is the role of a compressor in a pneumatic system?
To increase electrical current
To store hydraulic fluid
To compress and store air
To convert air into liquid
Which component is used to split compressed air into different lines?
Cylinder
Manifold
Valve
Restrictor
What type of cylinder has air pressure applied to only one side?
Double-acting cylinder
Hydraulic cylinder
Single-acting cylinder
Pressure cylinder
Which term describes the extension movement of a pneumatic cylinder?
Instroke
Outstroke
Reverse stroke
Exhaust stroke
Which type of valve has three ports and two states?
5/2 valve
3/2 valve
Shuttle valve
Uni-directional restrictor
What is the function of an actuator in a pneumatic system?
To compress air
To open and close valves
To store compressed air
To increase air pressure
What does an "AND" control require for a pneumatic cylinder to move?
At least one input signal
No input signals
Both input signals
A hydraulic signal
Why is an "OR" control useful in a pneumatic system?
It reduces air pressure
It allows control from multiple locations
It prevents circuits from operating
It only allows one input at a time
Which of the following can be used to create a time delay in a pneumatic system?
Manifold
Shuttle valve
Reservoir
Compressor
What is the function of a uni-directional restrictor?
To allow air to flow in both directions freely
To prevent air from flowing at all
To control air flow in only one direction
To increase air pressure in a circuit
What happens when the pilot air of a 5/2 valve is activated?
The valve switches states
Air stops flowing
The system shuts down
The pressure decreases to zero
How can you increase the force produced by a pneumatic cylinder?
Decrease the pressure
Increase the air pressure or use a larger piston
Use a smaller piston
Reduce the flow rate
Which of the following best describes sequential control?
Components in the system operate randomly
All parts operate at the same time
Components operate in a specific order
The circuit is manually controlled
What is the formula to calculate force in a single-acting cylinder?
Force = Pressure + Area
Force = Pressure × Area
Force = Area ÷ Pressure
Force = Pressure ÷ Area
Which actuator is activated by the movement of a cylinder piston?
Push button
Lever
Roller
Pilot air
What is one possible danger of working with compressed air?
It can cause overheating in electrical circuits
It can lead to air embolism if injected into the skin
It will always cause explosions
It makes machines operate too slowly
