Hydraulic and Pneumatic Systems

What is the principle behind hydraulic systems?

• Hydraulic systems function by using solid materials to transfer energy.

• Hydraulic systems operate based on the principle of gravity acting on liquids.

• Hydraulic systems operate on Pascal's principle, transmitting force through incompressible fluids.

• Hydraulic systems rely on the expansion of gases to transmit force.

Which component is NOT part of a pneumatic system?

• Electric motor

• Pressure regulator

• Air compressor

• Hydraulic pump

What is a common application of hydraulic systems in automotive?

• Transmission fluid

• Power steering

• Engine oil

• Brake fluid

How often should hydraulic systems be maintained?

• Every month

• Every 6 to 12 months

• Every 2 years

• Only when there is a leak

Which of the following is a key advantage of pneumatic systems over hydraulic systems?

• Faster response times and easier maintenance.

• Higher energy efficiency than pneumatic systems.

• Greater load capacity than pneumatic systems.

• More complex maintenance requirements than hydraulic systems.

What fluid is typically used in hydraulic systems?

• Oil

• Air

• Water

• Hydraulic fluid

Which component is essential for controlling air flow in a pneumatic system?

• Filter

• Cylinder

• Valve

• Compressor

What is the main disadvantage of hydraulic systems?

• Highly efficient energy transfer.

• Simple and low-cost installation.

• Prone to leaks and maintenance issues.

• Requires minimal maintenance.

In terms of force transmission, how do hydraulic systems operate?

• Hydraulic systems operate by using compressible gases to transmit force.

• Hydraulic systems rely on mechanical levers to amplify force without fluid.

• Hydraulic systems transmit force by using incompressible fluids to transfer pressure, allowing a small input force to generate a larger output force.

• Hydraulic systems function by creating a vacuum to pull force from one point to another.

What is the primary difference between hydraulic and pneumatic systems?

• Hydraulic systems operate at lower pressures than pneumatic systems.

• Hydraulic systems are used for small-scale applications; pneumatic systems are for large-scale.

• Hydraulic systems use liquids; pneumatic systems use gases.

• Hydraulic systems use gases; pneumatic systems use liquids.
