Understanding Hydraulic Systems

What is the primary fluid used in hydraulic systems?

• Air

• Hydraulic oil

• Water

• Glycerin

Which component in a hydraulic system is responsible for converting mechanical energy into fluid energy?

• Hydraulic cylinder

• Oil tank

• Electric motor

• Hydraulic pump

What does the relief valve in a hydraulic controller do?

• Stores the hydraulic oil

• Changes the flow direction

• Adjusts the fluid pressure

• Controls the flow rate

In what form does a hydraulic drive unit output its energy?

• Chemical energy

• Electrical energy

• Mechanical energy

• Thermal energy

What type of motion can hydraulic cylinders provide?

• Linear

• Rotational

• None

• Both rotational and linear

What is the function of the directional control valve in a hydraulic system?

• To filter impurities

• To adjust the flow direction

• To store excess oil

• To cool the system

What is the main advantage of using hydraulic systems in terms of force?

• Maintains constant force

• Decreases force

• Converts large forces to small

• Amplifies small forces into larger forces

Which of the following is a risk associated with hydraulic systems?

• Electrical shortages

• Overheating

• Oil leakage

• Freezing

Which industry commonly uses hydraulic systems for heavy lifting?

• Education

• Retail

• Construction

• Software development

How does the hydraulic system differ from the pneumatic system?

• Does not use any fluid

• Uses solid particles

• Uses liquid as the working fluid

• Uses air as the working fluid
