Aux 1 Unit 7 Q2

1 / 7

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

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

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.

2 / 7

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

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

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

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

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

3 / 7

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

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

B) Air reduces the weight of the system components.

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

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

4 / 7

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

C) Air cannot be filtered effectively.

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

D) Air increases the weight of the system.

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

5 / 7

What is another advantage of using air in pneumatic systems?

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

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

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

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

6 / 7

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

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

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

C) Air systems require constant lubrication to function properly.

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

7 / 7

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

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

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

A) Air contributes to greenhouse gas emissions.

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