1 / 7

What is the advantage of using air in pneumatic systems regarding environmental impact?

B) Air systems are more likely to cause spills and contamination.

D) Air systems require extensive filtration to prevent environmental damage.

A) Air contributes to greenhouse gas emissions.

C) Air has minimal environmental impact because it is naturally occurring and non-polluting.

2 / 7

Which of the following is an advantage of using air as a pneumatic medium?

A) Air is highly compressible and can be easily stored in containers.

C) Air is heavier than most hydraulic fluids, which makes it easier to control.

B) Air is readily available and does not require any special storage or handling.

D) Air has a high lubricating property that reduces wear in pneumatic systems.

3 / 7

What is another advantage of using air in pneumatic systems?

D) Air requires a complex infrastructure for distribution and use.

A) Air is highly flammable and can be used in explosive environments.

B) Air is non-compressible, which makes it ideal for precise control applications.

C) Air is non-toxic and safe to use in various environments, including food and medical applications.

4 / 7

What is a disadvantage of using air as a pneumatic medium related to system performance?

B) Air can cause inconsistent performance due to fluctuations in pressure and temperature.

A) Air systems are prone to overheating due to friction.

D) Air is highly reactive and can cause corrosion in system components.

C) Air systems require constant lubrication to function properly.

5 / 7

Why is the low cost of air considered an advantage in pneumatic systems?

D) Air can be easily liquefied for use in various applications.

B) Air reduces the weight of the system components.

C) Air increases the temperature of the system during compression.

A) Air is free and does not require processing before use.

6 / 7

What is a significant disadvantage of using air in pneumatic systems due to its compressibility?

A) Air is less efficient in energy transfer compared to hydraulic fluids, leading to potential energy losses.

C) Air cannot be filtered effectively.

B) Air is too dense for use in most applications.

D) Air increases the weight of the system.

7 / 7

Why might air be less suitable for high-power applications compared to hydraulic systems?

A) Air cannot be compressed to generate high pressures.

B) Air requires complex filtration systems to maintain its quality.

D) Air systems are prone to leaks, which significantly reduce efficiency.

C) Air systems operate at lower pressures, resulting in lower force and power output.
