What are Hydraulics?

What is the branch of science and engineering that is concerned with the use of fluids to perform mechanical tasks?

• Thermodynamics

• Hydraulics

• Pneumatics

• Electrodynamics

What does the Greek word "hydraulikos" mean?

• Water flow

• Water organ

• Water power

• Water cycle

What type of liquid is typically used in a hydraulic system?

• Compressible gas

• Incompressible liquid

• Organic solvent

• Water

According to Pascal's Law, what happens to pressure in an enclosed fluid at rest?

• It decreases with distance

• It is transmitted undiminished to only some points in the fluid

• It is transmitted undiminished to all points in the fluid

• It increases with distance

What is NOT a source of power in a hydraulic system?

• A hydraulic actuator

• An electric engine

• A motor

• A cylinder

What is the prime mover in a hydraulic system as mentioned in the document?

• A hydraulic pump

• An electric engine

• A hydraulic cylinder

• A pressure relief valve

Which of the following is an advantage of hydraulics due to the actuator?

• Variable speed

• Overload damage

• High compressibility

• Low power output

What allows a hydraulic actuator to be reversed without damage?

• Its high speed

• Its reversibility

• Its overload protection

• Its small components

What protects the hydraulic system from overload damage?

• Hydraulic oil

• Variable speed

• Pressure relief valve

• Small components

Why can hydraulic components provide high power output?

• Because they are easily compressible

• Because they are large in size

• Because of their high speed and pressure capabilities

• Because they use electric engines
